Bucky can't help it, he doesn't pull away, instead nosing at Steve's throat, taking in the alpha's scent. It's enough to calm him, because if this union is going to work, they need to trust each other. There's not much else he can do at the moment, so he looks at the moon.

"It's beautiful, isn't it?" he asks, because acknowledging he doesn't mind the comforting is hard; it's almost too intimate to admit, even if this man is going to be his mate by the end of the night. "I've always liked watching the moon rise on a full moon."

He still hasn't let go of Steven's hand.
