Teen Wolf's Derek Hale has a new love interest, and one dangerous fighting partner.

The ailing werewolf teamed up with the talented, albeit a tad mysterious, Braeden (Meagan Tandy) as his powers started to fade, and the supernatural mercenary has yet to let the team down. Despite her loyalty, Braeden entered season 4 as very much the stranger.

First appearing in season 3A, Braden was believed dead until she resurfaced in 3B. At the start of season 4, Braeden's character saved Derek (Tyler Hoechlin) - yet again - and it is for these reasons that Tandy believes Derek was so quick to trust the outsider.

"Derek knows she saved Isaac, as well as Derek himself and Peter," Tandy explained to My Fanbase. "There were plenty of opportunities for Braeden to show she had different motives but that never happened. She just came in, did her job, and left. I think Derek could sense that her actions were genuine."

Unlike Derek's previous relationships, it looks as if finally made a smart choice. Find out what Braeden and Derek will get up too next when the Teen Wolf season finale airs Monday at 10 p.m. ET on MTV.
