Gar has been moping since the disastrous conversation with Teddy. Even if he generally acted like himself it's hard to hide completely when you live in close quarters with people. And Dawn? She's good at noticing that sort of thing even though Gar generally refused to talk about it. The fact that it was about his boyfriend had ended up being confessed. She would have figured it out anyway since he generally talked to and about Teddy a lot and suddenly he hasn't been.

But Gar's got no suspicions when she drags him out of the tower and out to the park he sometimes hung out in. She sat him down on a bench with some line about him needing to stop hiding or something.
