His flesh hand touches the side of Steve's face, brushing at his beard with a smile. Just so he can feel the scratchy hair on his fingers. "Won't be the same without you," Bucky muses, trying to get that smile on Steve's face to return. As much as it pains him to stay here, it's the better option for the two of them, even if Bucky wants to be the one with Steve at all times, it's not possible. Not right now, anyway.

Maybe it will be easier, in the future. Hopefully the near future.

"But look at it this way: you've got a home to come back to." It should be obvious what he's trying to get at: even if Wakanda doesn't feel like home for Steve, even if he doesn't consider anyplace in particular his home, Bucky wants to be Steve's person to come back to. "I'll always wait for you, Steve."
