This starts with a flashback to when he Burnhams’ laboratory was attacked by Klingons, Michael’s mother donned the time travel suit to go back in time an hour and warn them of the attack. She instead arrived 950 years in the future to find all sentient life destroyed by Control.
Tethering herself to a nearby planet, Dr. Burnham made over 840 attempts to change the future, including moving humans to her planet, Terralysium, to test how she can change history.
Trying to stop Control from gaining the Sphere’s data, Dr. Burnham was responsible for it crossing paths with the Discovery. Now, the Discovery crew plans to upload the data into the suit and send it into the future where Control cannot access it, while keeping Dr. Burnham in the present,
More sprinklings of plot-oniom. Just when it seems Lyeland can be killed, he escapes.
“I like science,” says Spock, stating the obvious.
Tilly discovers a bio-neural scan of the Red Angel in Airiam’s code that matches Burnham.
Leland reveals that Section 31 built the Red Angel time travel suit twenty years ago in a temporal-arms race with the Klingons, and that Burnham’s parents had been part of that program. They plan to use Burnham as bait for the Red Angel.
OK Problem #1 – If the bio-scan matches Burnham and it turns out that it isn’t Burnham, does that mean that the scan was faulty ? Or did her mother use DNA from Burnham to deceive ?
#2 if they trapped future Burnham in a force-field with now Burnham, how was the doctor going to get in to administer help ?
It’s techno-babble in the extreme, and it all adds up to an interesting WTF ending.
