Logic extremists wreak havoc on interstellar politics.
Thrilling as they were, the episodes felt mildly lacking in the interpersonal department.
Its as good an hour as the show has produced yet.

Sarek, Spocks biological father and Burnhams surrogate parent, is departing Vulcan with a companion, Adjunct VLatak.
VLatak blindsides the eminent Vulcan when he declares that Sareks fascination with humans can no longer be tolerated.
The explosion rocks Burnham, literally.
Something of a mind-meld on steroids, the event forged a permanent mental connection between Burnham and Sarek.
Rocked by Sareks injuries, Burnham goes woozy and passes out.
In unconsciousness, Burnham travels to a memory from her teenage years on Vulcan.
and punches her into oblivion.
Burnham asks Lorca to help her find Sarek and, somewhat unexpectedly, the firebrand captain agrees.
Keeping Sarek alive and able to negotiate is key for Lorca.

The Discoverys crew plays a pivotal role in carrying out the mission.
Upon arriving on the nebulas outskirts, Lorca suggests sending out probes to ascertain Sareks location.
Saru notes that that process could take months and Burnham volunteersherselfas an alternative.
Again, Burnham suggests herself shell take a shuttle with a minimal crew into the nebula.
Burnham asks Lorca to assign Tilly as the science point-person for the expedition, and Lorca obliges.
I was supposed to be his proof that humans and Vulcans could coexist as equals, she tells Tilly.
My failure is his last thought.
To this point, Tyler has seemed a clear hindrance on Burnham, who tells him as much.
Burnham returns to thekatra-facilitated memory realm and convinces Sarek to reveal his regrets.
I never lost faith in you, Sarek instructs beforehand.
The failure in this day is mine and mine alone.
The ensuing scene is a doozy.
Sarek chose his biological child but wasnt transparent about the situation.
You made me believe I failed you, Burnham seethes.
Cornwell lambasts Lorca for treating Discovery like his own fiefdom and condoning Stamets eugenics manipulation.
Her language indicates her background as a psychologist, and Lorca uses it to escalate romantic tension.
Naturally, though, the Klingon peace overtures are a trap.
Klingons murder Cornwells Starfleet companions and the Cancri hosts when she arrives, and Kol beams in via hologram.
