Alec figures that if she's made it this far she can clearly handle herself, and doesn't bother to protest when Allison stakes her claim on half of their pursuers. "Deal." Otherwise, he's not very talkative during the next few grueling minutes as different guests come careening out of the dollhouse's nooks and crannies at them: he usually leaves the witty mid-battle banter to others. At one point one of Alec's stolen knives gets shattered in the grinding gears of a particularly tenacious cog droids' arm. Then he has to trade a shallow slice to the shoulder through the thick fabric of his frock coat in order to haul a burlap mannequin across his hip and slam it into the ground before it can get past him into Allison's space where she looks very busy fending off her own faceless—but not knifeless—opponent. At least he gets a second knife back out of it, though stabbing into a human-sized creature made of burlap as the follow-up feels very weird and disconcerting. Especially when it goes still after, laying in an insensate heap on the ground.

All in all, it's a bit of a sloppy showing, but truthfully his expertise in crowd control is at range and not in close quarters. Also, this is just a very weird day all around and he's maybe not totally in top form.

Then, as suddenly as it all began, the frenzy is over. Alec waits for a few more moments, standing still like he doesn't quite believe the struggle is done, before throwing a glance over his shoulder at the stranger. She fought as well as any Shadowhunter would, considering the array of tea party guests laid out around them. "Are you injured?"
