Hearing that panicked cry cuts Matt right down to the heart, and even though the sound of Harrow's paws shoveling heaps of snow out of the way is a good thing, it abruptly occurs to him how terrifying that sound must be to a child who's trapped and alone, claws scraping periodically against the door.

"Spider-man! We're here to help!" he calls out, wishing he knew the kid's real name, and hoping he's still with it enough to even register the words. "Captain America sent us for you!"

Better get the door open ASAP. Matt's not keen on getting in Harrow's way, nor freezing his own hands off trying to help, but the moment enough of the snow is cleared to let the door move, he's going to be in there swinging it open and beckoning Kinner to go first. Let them see a normal human face before they start bringing masked folks or werewolves into the mix.
