Official summary
Sissi, the school’s babe-in-waiting, plucks up the courage to tell Ulrich she has a crush on him. Far from being flattered, Ulrich bursts out laughing, hurting Sissi’s feelings. Determined not to be the fool in this situation, Sissi decides to get her own back by stirring up trouble between Ulrich and Yumi. While all this is going on, the X.A.N.A super-calculator has found a new way to attack our planet. It has contaminated the wasps on the school grounds and is using them to attack ! Yumi, Ulrich, Odd, and Jeremy will have to fight against this new menace. But Sissi’s meddling have sown seeds of doubt in the team members and it’s badly affecting their team spirit …

Detailed summary
In the Forest Sector a tower is activated. In the science building at Kadic, XANA takes control of a hornet and uses it to contaminate an entire hive…

Ulrich is reading in his room when a letter slides under the door: a love letter from Yumi which leaves the boy confused and distracted. Feeling pensive all day, he goes to the park alone to think…but the hornets target him and chase him through the trees… He warns the principal about the aggressive insects lurking in the park… Michel Rouiller goes to exterminate them and equips himself for the job in the tool shed.

But the bugs aren’t the least bit intimidated by the gas and chase after Michel before attacking our heroes again, who take cover in the buildings. Jeremy suspects XANA: the hornets were after them in particular…

The Scan detects the Tower in the Forest Sector which Odd and Jeremy decide to go to the factory to see to it… They warn Yumi via SMS…when she tries to warn Ulrich, he talks about the letter and tells Yumi that her feelings for him are reciprocated… The shock is intense when Yumi responds that she never wrote any letter… The mocking laugh of Sissi reveals all: the pest herself had faked the letter and planted it in Ulrich’s room…

The sewers are blocked by hornets. Odd and Jeremy retrace their steps and find a troubled Yumi and an upset Ulrich. But at that moment, the insects launch their major offensive and the sky over Kadic is invaded…
Students and fire fighters are powerless, taking cover in the cafeteria. The heroes make it to the factory, Jeremy having driven the insects away thanks to an ultrasonic machine.

On Lyoko, Aelita is close to the tower and is also chased by hornets, but virtual ones… The Lyoko Warriors are virtualised and confront the new menace…
During the start of the fight they are at a disadvantage because Ulrich doesn’t even bother to draw his virtual sword, still affected by the humiliation caused by Sissi.

It’s a few words by Yumi (“I know you’re unhappy, but there’s no reason to be, our friendship’s stronger than that, right?”) which makes the boy decide to respond: he annihilates two Hornets in one go and lets his companions head to the Tower. When Yumi is devirtualised, he hunts down and exterminates the Hornet responsible!

Aelita makes it to the Tower without any trouble while on Earth the hornets invade the cafeteria.
Once again the Code Lyoko saves many lives, stopping the insects flying in like darts… The Return to the Past is launched.

Back in time, Ulrich prepares for the moment when Sissi will slide the letter under his door, the boy opens it and Sissi flees, blushing like mad…

- Attack: Control swarms of hornets to block access to the factory and kill the heroes.
- Virtualisations: Yumi/Ulrich/Odd
- Visited Sectors: Desert; Forest
- Enemies met: Hornets (5)

- The return to the past stops the attack and erases memories.

- Ulrich makes his first love declaration to Yumi, misled by a false letter sent by Sissi.


About the characters

- First appearance of the groundskeeper/gardener Michel Roullier and Emilie Leduc, who plays a major part in episode 22, “Routine”.
- Emilie knows Odd keeps Kiwi in his room.

About errors

- Jeremy calls the groundskeeper Mr Bennet when his real name is Michel Rouiller.
- At the moment when Mr Rouiller leaves the shed the door is open the wrong way.
- The factory microphone disappears from Jeremy’s ear just before he says “Scanner Yumi”.
- Yumi’s outfit is reversed when she absorbs a Hornet laser with her fan.
- The door to Odd and Ulrich’s room changes colour in certain shots (blue, grey and green when it should be grey).
- Odd’s pants are entirely the one shade of purple when Jeremy talks about the groundskeeper, when he watches the hornets in the sewers with Jeremy and when he (Odd) opens the door to his room to find Ulrich with Yumi and Jeremy, and the colours are inversed during his transfer.
- Only episode in season 1 in which when all the heroes are virtualised there are no circles around them.

About the series

- French title: Attaque en piqué

- Same method of attack as in the previous episode.
- First episode in which all three heroes are virtualised at the same time!
- Only known episode in which a scene important to the plot was cut (see the official summary)… In fact, there was a link between a scene in which Sissi reveals her love for Ulrich and he laughs at her, which pushes her to send the false letter to get revenge…
We don't know why this scene was cut. It could be because of the morality: Ulrich mocks Sissi after the reveal without being punished; the example isn’t good for children…or maybe the writers thought this scene made Ulrich look bad…
The question remains unanswered.


Odd: Just imagine all the things she’s gonna learn when she gets here! She’s gonna be amazed!
Jeremy: I think about it all the time. I can’t wait for that day to come! (blushing) Hehe, yeah, it’s gonna…it’s gonna be great…

Odd: Ok guys, it’s time for us to work up a sweat!

Ulrich: Yumi! W-wait, I…I, um…are you ok?
Yumi: Well yeah? Why are you asking?
Ulrich: I just uh, just…asked! See you later!

Ulrich (reading a letter): Ulrich, I don’t know how to tell you this, so I’m writing it. I’ve always admired you. I’ve been wanting to tell you for ages, but I didn’t have the nerve…also, I wasn’t a hundred percent sure, but now I am. I love you. Signed, Yumi.

Ulrich: Oh, how could that have happened?
Jeremy: Hey Ulrich, don’t take this badly, but…your playing was kinda weird.
Odd: You could say that again! Why, even Jeremy was better than you today!
Ulrich: My mind wasn’t on the game, lay off, huh…

Ulrich: It’s just that…tch, well, I got this letter from a girl. The kind of letter a girl sends when she’s…
Odd: He’s in loo-oove! Hahahahaha! Ulrich’s in loo-oove!
Ulrich: That’s the problem! I’m not in love…I-I’m not sure I am…I can’t even manage to talk to her…
Odd: And can you tell us who the lucky lady is?
Ulrich: You gotta be kidding! I’m not telling anyone! One more thing, not a word to Yumi…I don’t want this to get around…
Jeremy: Uh…hey, Odd, did I really play better than him?

Odd (guessing): Milly or Tamiya?
Jeremy: No, they’re too young!
Odd: Claire! Sandra?
Jeremy: No, no, much too young! And they’re so…you know, they’re…they’re too uptight!
Odd: Hm…Emilie! Yeah! Yeah, yeah, it’s her! Look, I’m an expert with girls – she’s pretty, she’s the outdoors type – she’s the one who’d flip for him!
Yumi: Oh yeah, who is Emilie flipped over?
Odd: …it’s Jim! Emilie’s crazy about Jim!
Yumi: Jim? You’re kidding! Well they say that love is blind! (she notices Jim behind her) Oh! I uh…um, sorry…

Jeremy (talking about Kiwi): Don’t worry Odd, he’ll be back on his feet in no time! I mean, back on his paws!

Ulrich: Uh, Yumi? Come over here, please… I wanted to tell you something!
Yumi: I did too! They say Emilie’s in love with Jim!

Emilie: Ahem! What’s all this about me being in love with Jim?! (**Slap**) Start that rumour again and even your dog won’t recognise you!

Ulrich: No, no, wait, Yumi! I wanted to, uh…tell you something. It’s about your…about your letter.
Yumi: Huh? But-
Ulrich: No, let me finish. You said in the letter that…that you had certain feelings for me, and…I wanted you to know that…that I feel the same thing for you. There, I said it!
Yumi: But I never sent you any letter, Ulrich…
Sissi: Hahahahaha! Kind of embarrassing if you ask me!

Odd: Jeremy, any suggestions would be very welcome!
Jeremy: Uh, get away from here as fast as we can? (they flee, but are cut off) We’re trapped!
Odd: Hey, got any other ideas?
Jeremy: Jump! (he pulls Odd into the sewer water, then into a pipe on the other side)
Odd: This is your idea?!
Jeremy: Insects are very sensitive to smells!
Odd: They’re not the only ones, huh! Ugh!

Yumi: What’s that smell?
Odd: Ask Jeremy!

Yumi: Ulrich, this is all because of Sissi!
Ulrich: Don’t you think I know that? B-because of her, I’m confused. Every time I see you I don’t know what to think. So just leave me alone, ok?
Jeremy: He’s losing it!

Ulrich (talking about the hornet-repelling machine): Your thing stopped! How come?
Jeremy: Uh…battery’s dead!
Ulrich: What?!
Yumi/Odd/Jeremy: HURRY UP!!!

Sissi: Oh, and talk about embarrassing situations! I’m sure that Ulrich’s not about to forget this for a long time! What genius I am!

Jeremy: Ulrich, what are you doing?! Wake up, will you?

Yumi: Ulrich, are you with us or not? I know you’re unhappy, but there’s no reason to be, our friendship’s stronger than that, right? You can’t let Sissi’s dirty tricks beak us up, can you? So forget all about that, please! We need your help!

Sissi (caught by Ulrich delivering the false letter): Uhh…uh, hi! I-I was just passing by, and I…hehe…
Ulrich (taking the letter): What do you know? Let’s see now…
Sissi: It’s a…
Yumi: Well that’s a pretty embarrassing situation, don’t you think?
Sissi: I, er, this wasn’t the right door! Heh!
Yumi: It sure isn’t! Why not give it to Nicolas or to Herve? They’d be delighted!
