Yea that's the problem..
The show takes no risks - everyone "important" in more than a single episode - has come back.
Pike can't come back because the actor left the show, so they had to wind him up one way or another - and I always expected him to end up in the chair as every other ST storyline *always* ends with Pike in the chair; that's not changed. LOL
So no, they aren't about to write off the star of the show after two seasons. She's not dying. Sorry. I wish the show wasn't so safe, but it is. Whether its a good idea or not - they've turned ST into the Burnham story, so they aren't about to kill her off.
So whether the entire 3rd season becomes a redo of ST:Voyager (For the Discovery half of the story), while the Enterprise tries to "find" them lost in the wheres/whens or whether that gets resolved 3rd Season 1st Episode remains to be seen. Hell, we could wind up exactly where Season 1 Episode 1 started - only with a parallel universe Empress Captaining the Discovery (original character parallel character lol), and the characters on loan from Enterprise are back on Enterprise to only make guest plot appearances... (I hear Robot Chicken voice: "What a Twist!")
Or as the above poster suggested - ST:Voyager: The Burnham Years and just leave the native timeline universe behind entirely. Again.
Me and hubby have enjoyed the show - but much more popcorn-fun (I.e. no brain cells involved) than all the prior Trek series. CGI is awesome, but the ability for the writers to write for an ensemble cast is poo - they don't seem to know how to break out of a mostly-single-character story arc. At least First Season included more of everyone, even if it started with the shark-jumping plot of parallel universes. But unlike old star trek - no risk in the stories - all tension is gone outside of "how are they gonna wind up this problem in an hour" because we know they will and we know no one we know will die, at least for long.
:/
CGI won't hold it forever...
