Despicable Act (S01E07)
Saber scolded Shirou for not summoning her when he was in peril. She decided to accompany him to school. When Rin showed up and offered to walk with Shirou, Saber eventually agreed after Rin explained that it could trick their enemies into thinking it was a trap, making them less likely to attack. Rin informed them that there were spell marks around the school; if they managed to destroy them, it would delay the activation of the force field, though it wouldn’t eliminate it completely, and it might force the master to reveal themselves. After school, Shirou and Rin searched for and successfully destroyed several spell marks before calling it a night. On his way home, just after Rin departed, Shirou sensed a powerful presence and decided to investigate, tracing it back to the archery club.
