Hes unsure because he doesnt have his memories, and Im unsure because of the shock factor.
Full transparency, I was made aware of this spoiler back when executive producerJeffrey Lieber accidentally tweeted itmonths ago.
And yet, watching Hayley die wasnt any easier because of it.

And for those of you who genuinely didnt know this was happening, ARE YOU OKAY??
How that will come into play is yet to be seen, but Im willing to bet it will.
Okay, enough with New Orleans, lets get to the search to find Hayley.
Meanwhile, Klaus hits the road with Caroline when he finds out that Hope ran away from school.
And yes, shes with a boy.
(So maybe Gretas manipulation isnt a TOTAL lie.)
First up: The coffee stop.
As Caroline tells him, Congratulations, you just became a father.
And Caroline gets it.
And some were even way too old for me.Klaus:Im sure some had very pure intentions.
HOW ADORABLE IS THIS?!
Because sometimes you need technology to do what witchcraft cannot.
Klaus and Caroline then return to the car, which is where we get our second swoon-worthy moment.
When we met I was so young.
When I think about it, I was someone else back then.
And so were you, she tells him, before explaining all the ways that Klaus has changed.
Back then he terrified her.
He intrigued her, but he terrified her.
Now, look at how relaxed they are together.
Klaus has a follow-up question: Does she regret meeting him?
Again, the answer is no.
But I do think that I represented something for you back then, something innocent, she tells him.
It reminded you of a part of yourself that you lost and wished that you could get back.
If we had never met until now I wonder if youd even notice me.
To which Klaus responds, It would be impossible not to notice you, Caroline.
And once again Im smacked in the face with the chemistry between these two.
It was amazing when they first met, and its amazing now.
Eventually, they find Hope and Romans phones Hope ditched them on the side of the road.
(Also, come on Roman.
Its called a passcode, and its probably a good idea when youre keeping your identity a secret.)
But dont worry, Freya is able to find Hayley thanks to Hopes plan.
(More on that in a moment.)
And that brings us to the Hayley of it all.
My mom just wants peace, he says before revealing his backstory.
It seems Klaus is the reason Roman spent 50 years desiccating in a cave.
And yet, he still doesnt want to hurt Hope.
Because Hayley knows ALL about that.
Shell burn in the sun now that shes a vampire.
But Hayley knew that all along.
She just wants Hope to get to safety.
Thats why Hope is the one theyre after.
And yet, when Hope turns to leave, Greta arrives and knocks her out.
As Greta thrusts her hand into Hayleys chest, time slows down.
In that moment, she makes a decision.
The hour ends as Klaus and Elijah watch Hayley burn.
If Im being honest, Im not entirely sure how I feel about this death.
It wouldve been one thing if Greta had ripped her heart out.
If she was going to die, I wouldve loved to have seen more of her.
I also really need Elijah to snap out of it!
In fact, the Elijah of it all is what I might find the most upsetting.
If Elijah was going to snap out of it, that felt like the moment to do it.
