Spoiler for Sakura & Rin:

Rin must have an idea.. but then it makes you think did Sakura see Saber & Shirou outside her house at the time of looking Shinji, Rin's reason for being there shall be said whenever we get to find out more about Sakura.. and what Sakura said at the end of the episode to Rider.
