Hurrying up the stairs after the other man, Alistair frowns. "Is that what that thing you're wearing is?"

A gas mask. To protect him from whatever was in the air that could make them sick. It looked as suffocating as the templar helms he'd always hated, though with less concern about helmet hair. And less protection from blows to the head. But good for keeping someone from breathing in things that turned people into ghoul-like creatures. So, alright, useful. Maybe he'd be able to get his hands on one before coming back out, but even if he couldn't-

"I have to come back. Not here in particular." His steps slow until Alistair comes to a halt, frown deepening as he looks up at Steve. "I'm not going to just hide while people might be in danger. And if there's a chance I might already be sick I shouldn't be around others." Where he'd just be a danger to them. Though he was pretty sure he was fine. He hadn't been bitten and again, he hadn't seen any signs the air was dangerous. Even the taint wasn't that easily caught.
