All these years later Im still upset how they dropped the ball on these characters and that storyline. In case you dont remember the kindred were a group of witches who were keepers of insane witches in a supernatural mental asylum and they experimented in necromancy and immortality spells. Like so much potential right there but what happens is they are in 2 episodes and they arent shown or mentioned again to my memory. It feels unrealistic even in a fantasy setting cause they were so determined on keeping freya and rebekah(who was in eva sinclairs body) yet when they escape they just let them free, cmon.

And the fact they were messing with immortality spells could have led to interesting stories but again just another cool idea in a show that is going to be the equivalent of fan fiction and you never want that to happen.
