A part of him is still rankled at the fact they can't lock the door as it is now, but they're not the worst hit and he's more-or-less accepted that things have to be fixed in stages.

"Hey," is the immediate response - Walter does remember Sadie's new sensitivities, though she's had as much time to acclimate as he has, objectively speaking.

Walter's standing in the next closest doorway, looking at Sadie but not at her.

"If you get the door, we can have that hug now."
