Yelena & Bucky
He knew Natasha well enough but Yelena wasn't her sister. There was a good chance that she wouldn't take to him as politely as Nat. As the Winter Soldier, there weren't likely many good memories of him for her. Their time in the Red Room hadn't exactly been a fun time. But that had been a long time ago. They had both been different people.
His eyes lit up again as she continued speaking in Russian. Bucky even laughed at her response, turning to look for said dog. "Я бы разделил с ней свою еду. Вы думаете, она мне поверит?"
Plums. She'd brought plums. Bucky had to wonder if that was a coincidence or if she'd brought them for a reason. For herself? For him? He waited while Thor and Will got what they wanted and then shuffled a little closer. "Could I have a few plums please?"
