I am so excited that Matt is on board!
I really hated Logan, when I first started watching the show. I blamed him for everything that happened in Rory's life. Everytime, I got back around to season 5, I would go, HIM AGAIN! But I watched the entire series, so many times (so many times, I've lost count) I've really grown to like him. And now, I don't put all the blame on him.
I am surprised that, considering they have started filming, not all characters have been confirmed yet?
