Anon, I’m totally with you! I would much rather have the writers finish Adalind’s storyline in a way that makes sense, answers some questions, clears up some inconsistencies, and feels satisfying and worthy of everything that came before than just summarily kill her off and be done with it.
Killing her off would be lazy and wouldn’t even begin to do justice to the roller-coaster of an arc she’s been on over the last five years. No matter how they did it, it just wouldn’t feel like a good ending for her.
In fact, I’d rather the writers didn’t kill any member of Team Grimm…they’ve all had some incredible arcs, and just killing everybody–or even mostly everybody–at the end wouldn’t really fit with the tone and the story they’ve set up previously. So…yeah, let’s hope they don’t do that.
