Probably not as in-depth as you were hoping for but here's what i have for you at the moment:
Who is epsilon? Are they another character from your other stories or another unrelated work? Personally, it feels a bit sudden( not really the best way to phrase this) to name-drop this new character. Especially since it feels like they might have a more significant role in the future. Maybe having a slight exposition on how epsilon is may be helpful?
‘Even so, she was glad of their absence’.- a bit of awkward wording here
“mentally highlighting all the places the character sheet had mentioned "humanity," or the group being different from the other Jailors”
Is the character sheet you're referencing meant to be the descriptions of the characters at the beginning, the contents of the letter they received from epsilon, or both simultaneously? If the character sheet isn't the same thing they received in the first section you may want to go more in-depth about it
I understand Theta has a more positive outlook of the mtf after the interaction they had in the first piece, but it still seems like a bit of a stretch for theta to be daydreaming about joining them/ peace between the foundation and the Library after one positive interaction-Which is sort of briefly mentioned. So unless that's a plot point that has yet to be disclosed, perhaps consider adding a bit of hesitancy to thetas' thoughts? Perhaps they didn't regret sending that letter but are still hesitant about the foundation's practices while trying to be more upbeat about seeing potential friends again. ( hopefully, i'm conveying this thought well enough)
The interaction between theta and the curator is fine if just a bit lacking. Especially toward the end, just having a bit of visual detail thrown in there would help
Overall I'm kinda avoiding giving too much in-depth crit as I'm getting the feeling the story is currently unfinished. The last thing I'd suggest if you are going to add more is that the story could use a bit more descriptive flare in some places
