I just wondering, how the difference between Guest Cast / Co-Starring was made in this episode? Maybe some press-release or something?
There's some separation in the on-screen credits, some actors credited only at the end roll, and some credited at the end and at the beginning of the episode as well. But the guest cast at the episode page is separated differently (looks random to me, some significant characters was put in the co-star list).
Actually there's never was a co-stars in the previous episodes (because there's no co-stars in the credits), the listing was always done pretty much the same, guest stars only. Why is it different this time?
