I liked the episode, but it felt more formulaic than before.
I find these Vulcans to be a bit stilted, rather than cold. I wonder if Frain might do better without the American accent? Does it get in his way? Vulcan’s are tricky to get right. I’ve seen some very good actors miss the mark.
I think Vulcan’s are best played space Victorian Englishmen; all repression layered over self righteous conviction and more than a little condescension at times.
I don’t think that’s in doubt at all. He’s doing it for his own ends, even if he believes that no-one could handle the job of commanding Discovery and fighting the Klingons.
The Klingon mission was too convenient, it gave Lorca a potential solution, which worked out for him. What if that opportunity hadn’t been there? Of if it hadn’t been a trap? Those are questions we probably won’t get answers to.
