Uh. Losing people and more broadly, and more powerfully, being completely alone and isolated is one of Enoch's worst fears, more so now that he's actually experienced it in his return to Meridian's ruins. Losing Lucifel, and the fact that he's lost Armaros with Meridian, are parts of this fear that are mostly subconscious, but they'll get the strongest reaction if they're brought up.

He's gained a strong fear of flaying/seeing others flayed during his stay here in Animus - from mild anxiety to nausea to screaming and fleeing or even collapsing depending on the situation: who's being skinned, by what, how much, basically.

Additionally, though it doesn't manifest as blatantly as the others, losing his free will again is a tower-earned fear as well.

OH and I nearly forgot, there's a fear in there relating to Earth being gone too, which includes Heaven which implies God is dead, but this is something that got caught in that little psychological protective trap that means he logically knows it but the full emotional impact never hits. Know what I mean? Well, if Pitch can get ahold of it, he can play with it too.

And since I know you know his canon, if you want Pitch to go after things I haven't said here, he can do so!

You know I'm open for whatever! Fears, nightmares, even daymares if Pitch can do those. (yes that is a thing that exists, whatever spellcheck says)
