I gave that an 8. A bit of a step up from the last couple of confusing episodes, we had something with a (welcome) slower pace.
Pike saw his unfortunate mangled future on Boreth. I was already wondering about his fate at season's end, and now I think it will after what he saw.
I still don't understand why Tyler isn't on Qo'Nos now. He can still be on the show, maybe as a recurring character? He still seems like an awkward fit, even after L'Rell said his heart was after Burnham (blech

).
I liked seeing Reno back again, though it wasn't as annoying as her last appearance. It seems that she is a Stamets/Culber fan as well, like me, so she wants those crazy kids together again so they can work more efficiently. Learning about her dead wife was a nice, sad touch.
So far this season one of my highlights has been seeing Spock and Burnham interact, so I was happy they paired off again. The whole Control being inside the replica of the guy Burnham knew was intriguing at best.
The end was your standard countdown to destruction for the last two episodes. Of course the ship won't be destroyed, but it will be fun seeing the Enterprise and Number One again.
