as to reactions there's a lot of varying context I think about like, firstly in general I think it would be alarming in the sense of like Why is she in worm mode who blew her up!!! Cause that's not supposed to happen!

Assuming the most "she's fine though" causal context, unironically think N is game for anything, he's pretty unfazed by stuff being scary, it's more so a matter for him if a situation is scary? Idk if that makes sense? Like a monster is only as scary as the vibe is giving off, and if it's not attacking him he's fine with it. That's my legit read on him like canonically. Entering sex world I like to think she's a willing monster fucker, probably already super into wormzi so .. jorm is also hot. I think it'd be a fun mix up for some being-overpowered moments. N sees the cuteness in everything especially when it comes to his friends/lovers so I think he would compliment her for looking fab in monster form

Uzi it feels like a toss up heavily on the context but I lean towards also being pretty unfazed simply because Uzi makes it a point to not be scared of J. And was weirdly fixated on eldritch J, like at least mildly so, to have been like drawing her, I think she probably plays it off like Yeah Cause J is gross like a bug lol (and polycule wise that would be said lovingly like saying v is stinky). Would be fun to see her being really taunting to rile J up into getting feisty with her. I think she'd also be the most entertained (and turned on) by the thing you're saying about not ever seeing J looking anything but crisp n fresh ...

V I'm always inclined to think would be the most startled by the eldritch forms as anything that reminds her of Cyn's eldritch powers/forms particularly freaks her out and maybe even triggers her. I think if she was able to be calm enough to be like Okay no it's just J not Cyn .. she'd still be like NUH UH keep your appendages to yourself!!... UNTIL she sees Uzi and N doing having fun (many definitions for Fun in that context), gets pouty about feeling left out, and then decides to leave her comfort zone and get in on worm stuff.. and then also probably warm up enough to be like, actually it's kinda hot you look like shit rn, similar to Uzi lol
