That was a weird episode, and both main plot lines suffered from confusing twists.
I mean, I have no problem with Saru wanting to stay on the planet, even begging to do so. We had that a lot before in Trek. Also, the alien influence was very strongly hinted at. But now it was all his free will? What? In a way, that's worse than what Michael did, because at least she believed what she did was for the greater good. Saru wanted to feel well for a while, even ignoring that the Federation losing the conflict could put an end to that. At least I'd hope the planet is somewhat close to the border, with the Klingon ship getting there effortlessly and everything. Which maybe still shouldn't work, seeing as Burnham's mission is as critical as it is? Or is that planet outside Federation space?
The second plot line was even more confusing. Can someone tell me what was actually happening? Did L'rell want to get on the Discovery due to Voq? If so, that was a weird fucking way to achieve this. What was her plan after she discovered the Klingon corpses? How would it have played out in the ideal case for her? I really don't get that. She wants to destroy Kol, but what does it help to get back to him?
If she didn't want to actually get on the Discovery, that makes things even more weird, because she didn't get any information the Klingons didn't already know (remember, that was the reason why Lorca was abducted).
