Definitely looks like the kitchen that was in Sonny/Will's apartment, which has been tweaked to be JJ's studio apartment.I wonder where he is on the last day? Looks like an apartment we haven't
seen before. Maybe they're redressing the one JJ is in for others.
Looks like a dressing room.I'm not sure if picture was taken in make up room or his dressing room.
I'm guessing the actors can't always say what they want when they want to say it. Sometimes, they don't have a choice.
