Jack picks up on Henley's distaste, making a face of his own when he looks over and sees them. "At least he's got sandals, though those might be better off in the trash. We'll find him some over there." The last statement has the sense of agreement to it - and it is, considering, yes, he picked up on her intention.

"Less surprised he's got sneakers, considering gym shit. Just take those, for now."

The sandals are really sad.
