I feel like that part where sammy says she doesn’t even know when she realized she liked Yaz was probably because it didn’t happen in one moment, it was all the little interactions they had like always going on missions together, protecting eachother, and comforting eachother and she didnt even realize her feelings for her became romantic or didn’t want to admit it until yaz did
What gets me most about how Sam and Lucifer meet is like Sam very much is cutting off from human interaction and hates himself and what he's done so so deeply. he doesn't want to accept sympathy or care and he just wants to not hurt anyone else. But Lucifer comes as his dead girlfriend and she's not real and the damage is done and he touches Sam so softly and Sam is SO gentle and vulnerable about it while Lucifer reinforces Sam's ideology about isolation than reveals to Sam he is going to be the face of harm.
