This is a great story, one of the best I read outside of your newer stuff, though I agree with everyone we need a encore cause it a little too bittersweet with Dante getting left with "the Bad End". Felt like you had something set up for a "Lysa's Inferno". Though we never got it but can't blame you, you been pretty busy with your other works. Though would love to see a sequel or a new ending. Would be hard to see everyone just leave Dante in hell to suffer his fate. Even though they kind of hinted their was a way to get him back one day.

If I had ended it, I would had it so Judy had take his place in hell after a few days, rather then be his evil little nanny and the bittersweet ending would be due being actually turned into a baby. Dante would have to stay that way in Heaven and not able to visit Limbo again, while Lysa has to stay in Limbo and become ST. Jude new Aide and replacement in order for him to be able to go get Dante, as she slowly grows up to become the adult she never got to be in real life. Only to see the man she loves is now physically regressed to an infant, and fully dependent on others for his care.

The whole grown up Lysa but stuck in limbo forever and Dante getting to join his grandparents in Heaven but is stuck as a baby he became in Hell to make up for their "sins". Giving you the classic "Star Crossed Lovers" ending vibe, as anything they could have had dies in a sense. Cause even if Dante is an adult mentally. The baby body would be too much, even if sex isn't a thing in Heaven. I can just see it be close friends in the end.

Also think it would be cute that Dante's grandparents "cross to bear" would be caring for their little devil of a grandson for all eternity for the "sin" of flipping off the Big Man. I mean the Grandfather was the one that flip the big man off, but doubt the Grandmother wouldn't also join the punishment or at least demand to help. They went from trying to help potty-train the little guy to forever stuck changing diapers. Though I don't think they would care too much, and wouldn't doubt he would get help one day from their son and daughter in law. Would be cute to see the grandfather show off the son they lost came and grew to be a hero for others. Though sadly he could never grow up. Plus could see parents reaction to everything and how they would want to help too.

Plus the full circle of the baby treatment going from a like hell limbo, to truly hell, to a heavenly punishment would be the perfect bitterly sweet end for Dante that fits your style. Especially after Dante spends some time in Hell, like Limbo he would feel the difference between the three despite on how similar the treatment would be. The Angels professional handling of him, to an Devil's cruel torment while he stuck down there. To his Grandparent's affection. Especially when they know he is "there", he still helpless and still as dependent on them like baby. Plus wouldn't doubt he would need years upon years of emotional support from them. As doubt his time in hell would have been easy. Plus Dante might regress a bit or have some mental issues from his time in hell and need some babying to help comfort him like when he got to spend time with his grandparents the first time. (Plus to be honest if he fits the part by the time get fully get over it. I don't think he needs to be in "little adult clothes", it would be a waste in my option.)

Though you know what they say "hindsight is 20/20:, also "everyone is a critic". So just take them as free ideas, or suggestions if you don't have something planned yourself and keep up the great work.
