Hello POI GAF, I saw this thread and thought I'd pop-in. I've been watching this show for some years and am sad this is the last season, though it's better to go out on a high-note with an actual ending that to fizzle out or be suddenly canceled.
As for the most recent episodes, I knew that some people were going to bite the bullet before the season ended, if not all of them, but I always figured Root would be the first to go. After all, unlike the rest of the cast she didn't start out as a good guy/gal, she was a pretty bad villain. Thus, her coming out of the series unscathed and happy wasn't something I ever thought would happen.
I do say I am weirded out by how everyone seems to forget that she was a murderous criminal before The Machine changed her whole view point. I liked whatever episode it was whatever season ago when she unexpectedly encountered a previous victim of hers, even though he didn't know it, and had to deal with that. I feel like since then the show has tried to forget what she was.
Anyway, I'm excited to see how it all ends. Finch just needs to burn everything down.
