Burnham suffers a major betrayal while navigating among the Terrans.
But numerous curveballs and a key betrayal in The Wolf Inside cast her aptitude into doubt.
For better and for worse, the episode revolved around Lt. Ash Tyler.

Tylers compromised, Discovery trusts him, Burnhams still his lover, and so on.
Thankfully, The Wolf Inside ends this tedious dance.
Known as Fire Wolf, the Klingon and other rebel forces are situated on Harlak.
Terran General Order Four, a studied Burnham says upon hearing the news.
Any exotic species deemed a threat to the Imperial Supremacy will be extinguished without prejudice.
Sometimes the end justifies terrible means.
But Burnham isnt only fixated on the humanitarian aspect.
Lorcas order proves fateful.
Resistance forces predictably attack Burnham and Tyler upon their arrival on Harlaks surface.
What follows Burnham and Tylers surrender, though, is less predictable.
The prophet, it turns out, is Sarek, Burnhams adoptive Vulcan father in the prime universe.
She means us no harm.
The darkness of a Terran soul can now suppress the powers of a Vulcan mind meld?
Fire Wolf furiously asks Burnham after neutralizing Tyler.
Sarek stands by his assessment of Burnhams purity and she completes her objective but Tylers blown his cover.
I dont think Im Ash Tyler, Starfleet lieutenant, the officer says.
Tyler then reveals an unexpected twist: Not only is he compromised by the Klingons, hes Voq.
Burnhams rescued by Sarus Terran mirror, who serves as a nameless Kelpien slave aboard the Shenzhou.
The sentence isnt a final one for Tyler, though, whom Discovery immediately beams aboard.
Saru, meanwhile, has had his hands full aboard Discovery in Lorca and Burnhams absence.
(No matter that both of them hypothesize that an altered Stamets killed Culber.)
A scientist saved by his own specimens, Saru quips.
Naturally, Tillys procedure backfires.
We then see a mysterious scene of Stamets and his Terran mirror wandering through Discoverys spore forest.
So do Burnham and Lorca.
At the episodes conclusion, the two are engaging in a private interrogation in Burnhams ready room.
Burnhams initially shocked because the resistance forces havent had time to evacuate.
Her astonishment grows when the ship initiates a communication.
When I give an order, I do not expect to be ignored, the Terran emperor tells her.
