I feel like this was pretty obvious. Tyler is Voq. He was protecting the Klingon woman.
I'd love to be wrong, but it does feel telegraphed from a mile away. We'll see, though.
A few other things:
* I'm glad they went into a little detail of why it's essentially mushrooms (though special mushroom spores, really) that power the drive. As far as I'm concerned, sciency enough, let's keep rolling.
* My love of Tilly increases.
* I genuinely did not expect Stametz to step in for the tardigrade. Hooray, science ethics!
* I was also happy to see Burnham and Saru mend fences and begin to heal their relationship. It felt right to me.
* I loved Rainn Wilson's Harcourt Fenton Mudd.
* Captain Lorca continues to be a fascinating character for me.
* Are not Culber and Stametz
adorable together? ♥
* Tilly for best someday Captain. ♥
