Yes and No. Sugar Pool is a modern AU I've been making work about since s1 and is very personal to me, so before s2 premiered when I could already tell I wasn't going to like the direction they took Jinx my mind needed some separation between canon Jinx and Jinx in my AU and so I renamed her Jen "officially" to have a hard line between them. I think we naturally make characters ours when we create fanworks and this is especially true when changing the setting - and so Jen is practically an oc even if her origin was inspiration from Jinx. Still she can't truly said to be Jinx anymore, since a lot of the ways Jinx behaves in s2 Jen would never behave that way. But in a way she's still Jinx, because Jen was always just my interpretation of Jinx. Its confusing I know LOL. Anyway, I still often refer to her as Jinx to limit confusion. The official name of Jen mainly exists for my emotional well-being to remind myself that this particular character that was inspired by arcane is ultimately mine and the canon of arcane doesn't impact her. One day I may stop referring to her as Jinx altogether, maybe one day I'll completely rip Sugar Pool away from its Arcane soils and repot it, we'll see...
