Until now, I couldn't definitively pin down Lorca. I was mostly sure he was from the mirror universe. There was a moment in this episode that completely verified that all of the "where the hell are we?" stuff is an act. Burnham(was it Burnham? Maybe Saru?) suggests looking back through the navigational records to see what went wrong. He immediately cuts her off with his own theory and how to proceed, covering up his deed. This can only delay the inevitable discovery of his "override."
You know, I am the self-proclaimed World's Foremost Lorca Apologist...but yes...I noticed this as well.
I don't necessarily subscribe to the "Lorca is from the MU" theory, although I could see this being the case, but he seems to know more than he is letting on.He did cut them off, but I thought he gave them authorization to review the jump logs just not right then? He can only buy but so much time. I still hold out hope this is all for the greater good.
In the scene where he is discussing destiny with Burnham and he makes the comment "I'd hoped to find a better me here" (or something like that), the camera cuts to a shot of Burnham reacting with a look of puzzlement. It was like she was thinking, "that was a weird thing to say", which is probably exactly what most of us were thinking. That shot of her with that look has some meaning. Just not sure what that meaning is yet.
Aliens weren't treated as equals in the Ent MU. Although T'Pol was a bridge officer, at one point she feels the need to inform (can't recall who it was) that she was not a slave, which implies that she could have been. The conversation she has with Soval in the mess hall where he mentions that Vulcans are not permitted to give each other the Vulcan salute is further indication that aliens aren't seen as equal to Terrans in the Ent MU.There's a reason why I didn't like the previous MU episodes. One of them is that in a supposed Terran Empire, there were aliens on board being treated equally. That didn't make any sense at all. I feel that DSC is the first one to get that right. There may be aliens in the Terran Empire, but they're subservient species, not bridge officers.
