I do that too. Sometimes I fill in the blanks left by the storytelling. I imagine episode 15 cancelling the Klingon ship FX and replacing it with the story of the Federation counteroffensive on Starbase 1, using their tactical advantage to send a message to stay away from earth (they can remote auto-destruct the starbase and see cloaked ships while Klingons run their ships cloaked and unshielded). The bloodbath and retreat of the house at SB 1 (and lack of coordination causing similar bloodbaths across Federation space) gives Lrell something to show how far they have fallen without unity and honor in addition to the bomb.
I imagine the adventures in the Mirror Universe of the Shenzou as it is uniquely positioned to fill the power vacuum (Emperor Detmer).
I imagine an Episode 14 with Sarek informing Michael that her performance for the war effort (and his pull as the ambassador of Vulcan, who has the president's ear) is going to get her reinstated, making her episode 15 "mutuny" one of potentially massive consequence and sacrifice for her and her family.
I imagine episode 10.1, the adventure of Captain Killy: where the ISS Discovery has a 4 week journey, wiping the floor with the Klingon invasion fleet, destroying ~75 ships (as it has targeting scanners faster than Klingon shields can rise post-cloak and a mini-spore weapon system) and taking an entire house out of the war effort before finally being overwhelmed by a second house and lack of spore drive. The performance of the ISS Discovery and knowledge that it's Terran better explains Starfleet's willingness to empower Georgio.
I imagine episode 0.1-2.1, the adventures of Lorca, where Lorca hatches his plan with mirror Burnham, gets transported to a new universe, shaves his goatee, and then we see his internal monologue as he hatches a plan to gather a crew and a ship to return home.
I imagine episode 15.1 where the emperor returns home having seen how brutal Vulcans can be and decides to retake the crown with a new idea of pulling the Vulcan's out of the resistance and into full membership of the empire.
I'm making up my own stories in my head.
Right now I'm just imagining a flashback of Lorca with Mirror Burnham and Mirror Georgiou, in a backyard in the middle of the summer with a barbecue grill and their shades on while they cook whatever I'll leave up to your imagination. But they love the ribs. They're delicious. What exactly the ribs are? I'll never tell.
At one point, Georgiou's rubbing Lorca's shoulders as he eyes Burnham. Then he cracks open a can of alien beer, drinks it down, and thinks of dark, happy thoughts as the beer hits the spot. Then he kisses Georgiou.
Now I kind of wish it was summer...
