Can already hear the Trekkies going mad over the 'holodeck' appearing, even though it is basically just light projections (notice how they had to take physical guns into the holodeck? Also, they couldn't be physically hit), apparently something similar appeared in The Animated Series, which was also referenced last week, with Robert April (first captain of the Enterprise, before Pike and Kirk) being mentioned as one of the most well known captain's in Starfleet.
Thought it was a great episode, I was prepared to hate Captain Lorca, but he's definitely been through a lot of ****, feel sorry for the Admiral he pretty much sent to their death.
I'm liking Sarek's appearances, I've always thought he was a pretty interesting character, especially in TNG when Picard had to mind meld with him.
Seems like we will be seeing more of the bridge from next episode on
