Absolutely!

I hope it doesn't occur to her to harm you, either. But if it does, maybe she'll be warned by her prior experiences with the Elves, and forgo the idea. Should she succeed, the price of killing you again would be worse than what she experienced the first time, I think. Maglor is pretty formidable when he's angry, and not too scrupulous about how much suffering he causes an enemy. And I'm the same.

Nice there were a few things that could kill those deathly soldiers! Did Jon somehow employ one of these substances to that purpose?
