He narrowed his eyes at just how cold Match felt, and then stood and offered him a hand. "Come on, we've got to get you inside. We'll try hot water bottles and heating blankets first, and if that doesn't work I'm building you a bonfire." It was only partly a joke. He'd damn well do it if he couldn't get Match warmed up. He had thought about a hot bath, but whenever the serum wore off that might be disastrous.
Once Match was on his feet he'd put an arm around the other man's shoulders, both to offer some support and to try and add a bit of additional warmth. "Just gotta make it to the infirmary, alright?"
