We don't know if Blight really died. They did say his remains weren't found. And while Inque did get a lot of development, it didn't feel like enough. I felt like 10 from the Royal Flush Gang got more development than her in that sense. Still love Inque though. She's like Terry!Batman's Poison Ivy in a way where 10 is his Selina Kyle.
Yeah. I think they're mentioned as being part of a different continuity from the DCAU, but I'll still take whatever I can. Blight's return felt anti-climatic, but at least Inque got a more concrete origin after what vague hints were dropped in Inqueling.
I'm still waiting for a solid conclusion on Inque's story, though. In her last major appearence, both she and her daughter were dying, and I wonder what will happen next regarding them.
