I seem to recall them showing it up until the last summer episode which was gonna be part of the season 6 finale. Did they explain it closing? Did we see it again after that? My guess is they wanted to change the show and they cut that set out for season 7 as they wanted to focus on a smaller cast, yet still Michael and Peter were still there so I can’t see why they did away with it. The last scene I can recall in there was Coop telling Megan he was going to take the job in Philadelphia and then Lexi comforted her and they went to get coffee in the lounge.
