Remy!
The TV above the bar was playing the news, and while the people in the bar seemed to not give a damn, the news brought a smile to Remy's face. Since he wasn't exactly broke thanks to the summers adventures, he figured least he could do was buy a round for the bar.
When the bartender asked if there was a reason, Remy said it was his Christmas gift to everyone there. He felt like the universe had just given him a gift, so time to start paying it forward.
