I've been a faithful watcher since day one, but its often painful to watch some of the directions that show takes. I do agree that Chloe is being set up to die. I've even made the prediction that it will happen in episode 20. I'm not sure why I picked that one except that I think that's the direction the story is heading and I think they'll do it just prior to the finale simply so they can show everyone dealing with her death yet still be able to end the show on a high note.
That said, I am totally looking forward to "Legion" in January. The comic fanboy in me can't wait to see the first live-action portrayal of the best super hero team in comics history.
