"Hello, Buh... Buh..." Dean grunted softly in frustration, he was trying his best to learn other people's names. "Buh-Key! Dean is happy to meet Buh-Key." It wasn't a shout, but Dean seemed rather proud of himself that he learned a name in one go.
Though shortly after, Dean's head tilted to the side. While dumb as brick, he was actually pretty decent at reading people, he could see that Bucky was rather neutral to him, which was fine. He could also tell that Bucky was in some sort of pain. Again, Dean grunted as he reached over into the pouch he had on his side and pulled out a small vial full of green swirling liquid.
"Here, it is not Spicy Water, but it should help Buh-Key. Dean always uses them when Dean is in pain." He offered it to Bucky with a smile on his snout, shaking his hand up and down lightly.
