‘Supernatural’: Sam kills the werewolf he loved

Though Sam and Madison’s affair was brief, she was the first girl he started anything real with since Jessica. Unfortunately for him, she ended up not being just a girl but a werewolf, and he had no choice but to kill her, treating her like any other “thing” he would hunt. Though he could have deflected the responsibility to his big brother, he manned up and showed he had what it takes to take on any opponent.
