Railgun season 1 covered volumes 1,2 and 3. Which is the level upper arc (+2 filler arcs)
Railgun S is starting on volume 4, it will probably run through 5 and 6. Which will be the full sisters arc from the Railgun manga.
Index season 1 covers the first 6 volumes, volume 3 is the sister arc from the Index novel.
Railgun season 1 starts before Index season 1. Railgun S1 ends before volume 1 of Index ends. Basically, Railgun S1 ends around episode5/6 (whenever it was Touma was unconscious for a few days after being whipped by Kanzaki)
Sooooooo Railgun S is taking place between episodes 9 and 10 of Index S1. Episode 10 is when the sisters arc (Index POV) begins. Between episode 9 and 10(or volumes 2 and 3 if you like) there is a 2 week gap.
This 2 week gap is Railgun S.
So, is this scene from railgun season 1 episode 4 a filler scene?
she obviously knows who Toma is already, so this should take place after the beginning of index season 1.
