Time travel soulmates
I read a fic a while ago but can’t remember the name.
It was a time travel au, but Pandora made it so her and her friend group (Barty, Evan, Dorcas, and Regulus) could go back in time to like- I think their fifth or sixth year, but the catch was that it also brought their soulmates back (they all went back in time when they died, so Barty had lived longest the first timeline, stuff like that) and so Barty and Evan were already soulmates so they were fine, Dorcas was soulmates with Marlene so they got her so they could explain and then I think Xeno was Panda’s soulmate and they just collected them to catch them up on what was going on. The thing was they didn’t KNOW who Regulus’s soulmate was so they were like: I guess when we find them we should tell them (they all woke up on the Hogwarts train) meanwhile in another part of the train, a newly dead now alive James Potter is looking around the compartment in utter confusion.
