Not a medical issue you say? Locked door you say? Acting like my old theory that Bella is a time displaced Dr McCoy with a holo emitter to make him look like the second most attractive older woman in the game (good thing I'm already in witness protection from the Bella fans) isn't valid? Doesn't matter if the door is locked when you can just transport into the room. Dammit Mormont she's a doctor not a librarian!
She does indeed teach Research Tools to the 2nd years.
Heck, she might even have the knowledge of embalming and what we all saw is the embalmed corpse of her husband.
Seriously though, look at her, more importantly look at her tits. Which part of her does not scream MILF! I bet that is why Jade hates her more than Cathy when Stephen shows interest in Bella. Let's get one fact straight, they are both MILF while Cathy is a cougar. She sees Bella as a direct competition, one who is married to boot. She's more upset about Stephen just mentioning Bella than him banging 3 students. Now I'm more inclined to Bella losing a child and she and her husband blames each other and are estranged, and that room is the child's room.
All along, this game emphasizes on one thing, as Neil whatever-his-last-name says:
Follow your fucking heart! It applies to all the characters, Jill and her heritage, Bella and her conflicted heart, M/J and their "inclinations", Sage and her love for Chad or MC, MC on whether he should keep his snake in and who to bite, even Cathy and Jade. All of them have their inner conversations on whether they should proceed before actually do something like getting on Swyper or have a fling with the MC. DPC has the warning in the intro, this game is not for those going through a difficult time, because if you followed your heart and made your bed, you might not be able to accept the consequences later on. This game will break you. (That is why we all fap to the gallery and not in-game, it's too dramatic)
