Shawn is not going to die in nightwings run! Its already confirmed she wont be fridged by Seeley. Now whether or not she will stick around as his girlfriend. we dont know! Personally i hope she doesnt stick around as his girlfriend because Dick deserves better than the current writing he is getting. I know Batgirl writers are pushing DickxBabs and even Seeley pushed them in the beginning of the run, but both dick and babs deserve new love interested that we all can get behind!
This is the first time I’m hearing about Seeley saying she won’t die and I can’t seem to find an article discussing her fate. I would love a source if you have it.
As for the DickBabs thing I wouldn’t mind them getting back together. They’re one of my absolute favorite pairings. I view the DickBabs pairing the same way I do CatBat. It’s a pairing as old as the characters themselves and the canoness fluctuates but yet the writers never fail to bring them back together in the end. The likelihood of DickBabs going away completely is slim to none, especially since they were canon for so long and even engaged before New 52 came around and messed shit up.
