The intro of "To Sir With Love." Upon learning that there's a wraith haunting Innsmouth Academy as a result of his early magical experiments, Headmaster Montag decides to kill himself in order to banish it... whereupon Usher and Carter immediately refuse him. Usher and Montag's professional relationship might be eccentric at best, and Carter doesn't have any reason to see him as anything other than a creepy teacher with a habit of giving nightmarish lectures, but they're not ready to let him die- even if it's for a good cause.
Unusually for Montag, he actually manages to seem proud of Carter when she admits to knowing the exact details of the sacrifice he's about to perform.

We're pretty desensitized to adorable cats these days, but replace "cat" with "cat-sized undead moth" or "dog-sized squishy blobby big-headed tentacle thing that jumps up and down," and you get some really weird d'awww moments.
In Blue Mountain, Eleanor Franklin appears to be curiously uninformed and untouched by recent events. When speaking with her about the Fog it is implied that her deceased husband Ed saved her life by keeping her inside the house. In a game where the ghosts are largely angry or malevolent, it is a testament to the love Ed still holds for his wife that he actively tries to protect her.
