So am I to assume that there's no definitive proof that Stewart was renegotiating his contract after Season 3? Stewart thought he'd be fired? Where can I read about this?!?!?!
Anyway, I would NOT have wanted Shelby. She ended up ok, but to have her be the new XO permanently would've been "Kate Pulaski Part II". I just don't see that character meshing with the others.

The script doesn't address it explicitly, simply refering to him as "science officer", but Sonak does have the stripes, so it's not unreasonable to assume he might have been in the running for XO under Decker:
