At the first blast, Teddy was looking around wildly. That was certainly an odd cue for an explosion. Maybe Dr. Strange was taboo in this dimension. By the time they were hit with the most immediate explosion, Teddy's skin had hardened, reflexively turning his Hulk green and growing to be barely shaken with the impact, his head tucked under his arms. Before the ringing in his ears had stopped, he was reaching for Billy's arm, shaking dust from his hair and pushing his boyfriend towards the blown out window. He needed to get into more open space, Teddy was the one who could take the blast if there were any more bombs in here, and someone needed to try to get control over the chaos out there.
"Been through worse," he assured Billy, but the innocent diners couldn't say so much. Who would have thought the Hulk hadn't taken out enough of the city?
