I'm onboard with this plot but only if they find a good reason that explained how he survived. It wasn't until Henrik died Esther came up with the Vampirism Spell and she didn't look like the kind of witch who enjoyed dark arts, she merely did it that one time to try and protect the rest of her family.

And if they bring him back, they had better bring him back as a main cast otherwise I find it a waste of a potential, interesting character.

Well I have a theory about how Henrick could come back maybe Esther tried to bring him back but thought she failed and he didn't come back until long after his family left. And over the years he discovered a way to prolounge his own life with sacrificial magic. Like using a spell that takes the life span of another and adds to Henrick's life span.

That sounds like a good idea, bringing forth a long lost member of the original family in Claire holt/Rebekah's place. To continue the story of The originals. I wouldn't suggest Henrik if they could somehow manage to pull off Ester or Mikeal having a child before their initial marriage peferably a girl to fill Rebekah's female lead role in the original family. But then again Haylay is having a baby girl so that might fill the role if She has inhuman growth which would be great. But none the less they need another one of their family members to be in the story with them. I was hoping they would find a witch to lower the vail like Bonnie did and bring Kol or Finn back. But Kol has a lead role in the new Supernatural spin off series: Supernatural Bloodline. Finn wouldn't be much of an addition because he seemed a bit of a boring Original. Either they could bring in a Aunt or Uncle or cousin of the Original family, that would definitely bring a new prespective and angel.

Hmm, that's incorrect. Elijah himself said Esther practiced Dark Arts and clearly not only for doing one very complicated spell that turned them into vampires.

When did he say that? I find it hart to believe Esther wouldn't turn right to her Dark Arts after Henrik died yet she asked Ayanna for help. She obviously had to take experimentation and ingenuity into consideration, that doesn't sound like one who practice it on a daily basis with experience.

First episode. He specifically says she practiced dark magic and also used it to turn them into immortals.

He specifically says dabble. This is nitpicking but that word usually implies "slightly use" and not grand experience but I might have misunderstood what you meant. I don't think she was much a "dark wizard" prior to Henrik's death, perhaps trying some now and then see what she could do. If she was that experienced why would she ask Ayanna in the first place?

Yes, perhaps she wasn't very experienced by then but I'd bet she eventually got along with that sort of magic seeing how she often uses possession and that doesn't seem like "good" magic. Not to mention the curse she put on Klaus. Regardless we're just speculating. Elijah said she practiced dark magic, if she did it often or not we can't say as fact.
