I'll say sorry in advance if the answer is a bit confusing but I'll try and explain it the best I can. Also, Zinfandel and Coretto belong to @stankychee but she said it was okay for me to talk a little about this part of Zin's background.

Reverse kidnapped Corretto because he looked like a Papyrus and was very easy prey; young, a bit frail-looking, and friendly enough to approach and lure closer. But Zinfandel and Corretto are from a Swap AU (Outer!Fellswap Gold with a dash of Warhammer 40k inspiration) and that made Corretto a Sans-coded monster instead of having a Papyrus-coded soul, something Reverse was not aware of at the time.

You see, to fix Ghost's (Reverse/Rewind's brother) broken soul, Reverse needs a Papyrus-coded soul to fill in the missing data and also give Ghost a new body that is attuned to the new coding. It can only be a Papyrus-coded soul and body... Nothing else.

So after successfully kidnapping Corretto, Reverse tried to combine Corretto's soul with Ghost's and it failed horribly because the souls weren't compatible with each other. The failure, along with Reverse's stubbornness and denial, resulted in Corretto's death and Ghost's soul getting damaged even further. It was not a merciful death for the younger monster...

All good!

I don't know all the details about Outer!Wine because he isn't mine but I'll do my best to answer any questions related to him. Quick summary: Outer!Wine aka Zinfandel is @stankychee's character and inspired by Fellswap Gold and Outertale, along with some Warhammer 40K aesthetics. His AU takes place on a space station instead of the moon and has a strong military vibe.

Now, Zin had a little brother, an Outer!Fellswap version of Coffee called Corretto, and Reverse stumbled across this poor soul and kidnapped him, believing him to be Papyrus-coded. Zinfandel witnessed the kidnapping but was unable to stop Reverse from escaping the AU with Corretto. Unfortunately for Reverse (and the poor kid!), Corretto was a Swap version and therefore Sans-coded. He suffered a horrible death as his SOUL wasn't compatible with the broken SOUL of Reverse's brother, Ghost... A damn tragedy and a hard-learned lesson for Reverse about Swap AUs; Sans and Papyrus-coded souls don't mix well, if at all. (PS: this is headcanon lore! It's fine if you believe differently.) Zinfandel has been tracking Reverse down ever since, chasing him down through the multiverse.

How he does it? Zinfandel has this very cool sword that works almost the same as Rewind/Reverse's ShortCUT scissors. It allows him to create (temporary) exits and entry points between AUs. He follows traces of tampered code within AUs to try and follow Reverse (every portal Rewind/Reverse create leaves behind such traces).
