I honestly thought we'd have to cut this picture when I first saw it because I had no idea where it was supposed to go in Steve's script, but there was so much happening at once at that stage, I was just like, "Okay, this is supposed to be an ending I guess" and let you keep rolling with it.
It finally clicked for me once we added it into the game though! It's just a goofy little send off for a couple of gays about to hit the showers together.
