Bucky would still make a mental note for the next time he was baking. Or he'd find something, some way to pay Ciri back for her kindness. For now, a short nod would have to be enough to show that he was grateful. "Uh, yeah, would you mind giving me a lift, eh, down?" He wasn't sure where that door would lead. Though he felt he knew the hotel pretty well, he hadn't been up here and getting lost didn't sound like a fun time.
"Just the lobby is fine, if you could." Portal hopping wasn't his favorite mode of transportation but it sure was handy. Her thanking him made him blush a little. Bucky didn't feel like he had done much but he was glad that he'd helped her in some way.
He used his good hand to take her's and held his breath, waiting for the familiar rush of magic as they stepped through a portal back inside the hotel.
