I have a few Corrections, First and Foremost, the one who's targeting the school is Medusa AKA Rider, who's controlled by Shinji Matou, not Caster, Caster took over Ryuudou Temple and has practically nothing to do with the school other than her Master. Secondly, Between Rin summoning her Servant and Shirou summoning his, There is approximately 1 and 1/2 to 2 days between them, After summoning Archer, Rin will have a conversation with archer before going to sleep, She would wake up the next day, And go search Fuyuki in hopes of potentially finding signs of other Servants, But she would not find anything, She would go home and sleep, Then wake up the next day, Go to school, Only to find a Bounded Field around her school, She would spend the day secretly searching the school, But also attending it to avoid suspicion, She would only take action at Evening/Night, Where she would encounter Lancer, And fight and blah blah blah, I don't think I need to explain the rest, Only that Shirou would summon his Servant after this. Thirdly, Shirou uses his nerves not his veins as Pseudo Magic Circuits. And just some advice, you can look most of this up on the TYPE-MOON Wiki very easily, it is actually a great Wiki, and thank you for the chapter, Well that's it, I don't have more to say.
