Spoiler alert: This post contains plot from the season 4 finale ofThe Originals.

Something was able to separate the Mikaelsons for good (or at least until season 5).

But one sibling took things a step further.

And so Marcel compelled Elijah to forget the always and forever vow, to forget his siblings.

In other words, he erased the most fundamental aspect of Elijah.

We talked to Narducci about the episode and saying goodbye.

ENTERTAINMENT WEEKLY: From the beginning, theres been talk of this show being about Klaus redemption.

I knew at some point somebody was going to speak those words.

Im so interested in the decision to have Elijah basically erase who he is.

And I think Elijah commits a form of suicide in the finale of season 4.

Will that be a good decision for him or a bad decision?

Will he find himself enlightened, or will he spiral into madness without his siblings?

That remains to be seen, but I like the glimpse of him playing the piano.

This unfortunate truth has haunted me for as long as I can recall.

I thought that thats as close to a heroic act as a 1,000-year-old vampire killer is capable of.

They have a thousand years of story.

I think season 5 will be the best season yet.

Im excited to be a fan and to watch it.

Im interested in the timing of the decision to have Hope attend Alaric and Carolines school.

Its really tragic in a beautiful way that she refers to Marcel as her friend.

When Julie pitched that idea, I think I just sat back in my chair and smiled.

It has been a true pleasure.

The fans have been fantastic.
