I'm very late, but I have watched it just now, by the way I gave a 9 to this episode because I enjoyed it quite a lot, with that aura of suspence and mistery always floating around, and even more, ther rpg structure starting to slowly revealing itself
(overall, I'm a lover of rpgs)
I also think that the characters are very well done, both in character design both in their behaviour. Rin is indeed very a beautiful and lovable person, but I guess my preference, as for now, goes to Saber goddess
Overall, strong improvement from episode 1, and I'm sure this is just the beginning
