Strange has started giving Pumpkin some well deserved scratches and is about to go into a little whoosa woosa good dog, issit you, yes it's you when all of a sudden, he's yelled at from two different people. His eyes just bug out for a moment and Strange just instinctively backs up because again! He's getting yelled at! And he's getting yelled at over something stupid?

Honestly, it's not completely out of the ordinary that someone would make a mistake like that. The haughtiness kicks right back into gear as he pushes back that surprised expression for one closer to his normal annoyed.

"How was I supposed to know that?" he grumbles, gesturing back at Pumpkin. Come back here you little fluff, it's okay, the yelling's stopped. "You don't look a thing alike and you share the same last name. Of course someone would assume married over siblings."

At least, of course the man who doesn't have any siblings in both realities and was also married in both realities assumes married over siblings.
