To call what Prompto gave Liz's hand a squeeze back would be incredibly generous, but, hey, at least it was something?

"No, it's okay," he said. "Thanks, though. It's....fine. I'm good."

Liz had already done more than enough for him, and then some, all that worrying and taking care of Noctra and helping him get out. He really shouldn't keep wasting her time. And tea would mean having to sit up to drink it, and uggghhh.
