I can totally picture Jonas Hanson getting progressively kinkier & creepier, to the point where Sam wasn't comfortable with being the sub to his Dom, and breaking their engagement as his sexual douchery overlapped into other areas of their relationship.

In my fanon, Sam lost her V-card as a teenager during a rebellious phase. Because by the time she was "touched" in Broca Divide, the sex-tigress who attacked Jack in the locker room KNEW HER MOVES. And Jack was sorely tempted. Hell, if I were in Jack's place, I'd've done her & claimed later that I was "touched" too.

PS: Daniel totally did threesomes with Stephen & Sarah in grad school.

PPS: Sam's Doe Eyes never fail to make me melt. DOE EYES 4EVA
