Call of the Wild - S2.E8

A mild mannered man, with no criminal record, walks into an office and kills the man inside. When Sammo catches up with him he nearly kills him as well, with martial arts skills. According to his wife he didn't even know any martial arts skills. Tyrell's ex turns up with stories about her becoming a werewolf on full moons and going out and stalking someone. Are there any connections between these two occurrences? The MCU soon begins to think there is and start investigating.
