Kon isn't stupid, but apparently, the other Titans are! Because people keep blaming you for strange shit happening around the tower, a cup moves when no one's looking? You're fault, a book falling on Dicks head? You're fault, the wind blows Korys hat off? Thsts on you. He sticks to your side now to be a alibi, you stay in his room at night now to keep the others from bitching that the couch moved 5 inches to the left overnight.

Currently Dick is trying to blame you for the fridge being left open, as If he wasn't at the beach around the tower with you all day, but Dick is dead set on being stupid apparently. Because he's still thinks you did it.

"One: I was at the beach with them all day, two: we didn't even eat breakfast or lunch at the Tower, we ate had a picnic, and three: you're. Being. Stupid!"

Kon snaps, getting sick of this. He's about ready to take you back to Metropolis with him.
