Excellent to know everyone was right about Tyler being Voq. It became more and more obvious with every passing episode. It's especially hilarious that the tribble on Lorca's desk played absolutely no role in uncovering him
I haven't read what you've all been saying the past couple of episodes, but I'm guessing we're all on the same page with Lorca being mirror universe Lorca? I'd say this episode finally started to tie that in—that absolutely was a little smile at the end when the Emperor came on screen. It's all part of his plan to see through his coup. All the speculation over Voq/Tyler is essentially the red herring, and the main not-who-he-says-he-is has been Lorca all along.
I'm guessing the rest of the season will be about Lorca continuing to position the pieces for the coup through the unsuspecting Michael, her finding out, Stamets and Stamets finding a way back home, and her killing Lorca (or letting the Emperor do it). That way by the start of season 2 Burnham will be captain of the Discovery back in our universe again (since I assume mirror Lorca killed real Lorca when he first came across).
Oh, and mirror universe number one (I don't know her name) is totes starting to suspect Michael isn't what she says she is.
