How would the Originals react to seeing one of their dead siblings alive?

[MrAnonymus]

I've been wondering how do you think the Originals would react if their youngest family member Henrik that died as a human suddenly made a reappearance? For those of you that don't remember Henrik he was the youngest sibling and he died when he and Klaus went to watch the werewolves turn on the full moon. I've often wondered if it was possible that he somehow got brought back by Esther who never realized she had succeeded(like it took him a day or two to wake up) and when he woke up he found everything he knew gone or in ruin. Then spent centuries seeking out his family but always being one step behind.

Now if they brought Henrik back I'd like him to be like a frightning figure possibly a warlock that sides with nature but believes it's humans that must be destroyed if only to see how other members of his kind react to a reverse way of thinking. Perhaps give him a Darth Maul like personality making him very calculating and vengeful.
