Mike has the sense that the dimensions and proportions are wrong, too. The ants seem unconcerned about such things, intent upon turning the house into a huge anthill. But... things seem off. The apparent wall between this house and the next seems much closer than it should be, but he sees no sign of a room to explain that. It makes him wish he'd investigated the normal interior of one of these row-houses before coming in here. If he does something like this again, he'll remember to do that.

He makes his way to Eddie's location, and plays the light over the sealed staircase.

"I'd say we need to treat that like a dead end. I don't think these little ladies'd take too kindly to us demolishing their handiwork. Anything about these dimensions seem wrong to you?"
