I Was a Sixth Grade Alien - Season 2 Episode 17 To See the Invisible Geek!

Tim is over at Pleskit's house and Tim finds out about the Invisiblunker. Pleskit brings it to school the next day, and Tim uses it to try and find out more about Lindy before she moves. He tries to impress her, but it all goes down the drain because Lindy thinks he's just plain weird! When Lindy and October are in the girls bathroom, Tim follows them, and overhears October ask Lindy what she really thinks of him. After Lindy states that she thinks Tim's a dork, he wants to stay invisible forever. And that could be possible if Pleskit, Mcnally, and Lindy aren't able to find him soon! In the end, it turns out Lindy really does like Tim, but unfortunately it's too late for him and Lindy to become anything.
