[He may not like her, per se, but the Principal did shove her into a washing machine, so.]

I doubt anyone'd be ganging up on you right now, though. So I wouldn't worry too much.

[Also, she's not Sally, so he's not falling for it.

That and also, because he's kind of not noticing. He's just checking her arm to make sure it's ok.]
