[Lyn - like everyone else - has heard about the angels. And, understandably, is freaked the hell out by them. His speed has allowed him to get to school without incident at least once since they arrived in Mayfield - enough that he won't get droned, which was the whole idea - but he's barely ventured past the door of the house beyond that.
However, he saw the Postman delivering packages today, while he was keeping vigil against the angels. Packages mean regains...possibly even demonic powers he can use against the angels, if he can get the fuck out there and get them. He agonizes over the risks versus rewards for nearly an hour before, in an impulsive fit, he bolts out the door and to the mailbox, grabbing the boxes there and booking it back inside with them as fast as demonically possible.
Christ he hopes he didn't attract their attention.
He tries to distract himself from his paranoia by looking at the packages. One's for him, and one's for Legault...who he's been avoiding since Valentine's Day anyway, because that was possibly the most awkward thing ever. He focuses purely on his own package, ripping it open to find...oh, shit. Decent fucking clothing. Hell yes! He'll actually strip down and start changing right there in the living room, not that anyone's around to see it.]
