Luckily the house is exactly where Arthur wanted to meet him, but he's still a little surprised by Bucky's choice of entrance.

Still, he opens it just a few seconds later: he doesn't wear his jacket inside so it's his vest and sleeves rolled up, obviously no eye contact when he gives a dry smile to Bucky but not using his cane either, since he actually knows his house now.

"Hey, Bucky. Come in, please." Better to talk with the doors shut, after all.
