Prompto definitely did not drink coffee. He was eight. What kind of psychopathic eight year old drank coffee?

"Juice sounds good," he decided, with a nod. "T-thank you."

And he would have moved toward the table to have a seat, but he was in a bit of a conundrum, because that meant setting Rain/Kitty down and he didn't know if he was ready to do that quite yet.
