Lennon was ready to stop talking about the markers, because it was making him worry about who it could possibly be-- if anyone-- and how Chase and Edwin were feeling given that Kiley and Oliver weren't here with them. Pam's question and Felix taking his socks back off made him realize that no, he didn't have anything else to wear. With a soft sigh he began taking off his shoes and then his socks to put in his backpack. He hadn't had the presence of mind to grab any extra clothes because yeah. Monsters.
It wasn't surprising that Owen was the one to volunteer to see about the markers. Selfishly, Lennon just hoped that Chase didn't decide to go with him. At least he didn't think Tobias or Felix would offer, and he wasn't. He'd had one scary expedition and wasn't eager to repeat it. Maybe it was nothing. But maybe not.
