He opens the wrong door. There's a million he could pick, a million upon a million and its not a world he knows that he steps into. The woman sitting at the table of the house he's crashed at in Vancouver more times than he can count is the woman he met in the tower, the version of himself who slouched over the table in the kitchen and ate oatmeal with chocolate and--
She doesn't recognize him, so it must be the wrong world. There's as many as the stars so she isn't the version who met him in the tower. That does explain why she's holding up a spoon like she'll shish kabob him with it. It must feel as wrong to her as it does to him. Two nations vying to represent the same people. He reaches back for the door but Canada walks around the corner, drawn by the noise and an exasperated 'oh god what now America' on her lips when she draws up silent.
Recognition flashes in her eyes. She bites her lip and shakes her head.
"Thought it was a dream."
His grin is stupid but genuine and the female America is forgotten. She's just the same as in the tower and he asks if she wants to come back for a visit--it's nice and safe and he sort of missed her pancakes, his Canada makes some but they're not quite the same.
She rolls her eyes and pushes him through the door, asking him how things went, where everyone has gone and how things have been.
America watches her sister-neighbor walk through a door that hadn't been there before and...she sits back in her chair. She picks up her coat. She heads home.
Canada must have drugged those stupid pancakes again.
