[x] Shikigami
Gotta rack up them Touko points. She's actually difficult to keep around, wheras Zelkova is stuck with us.
Also, it was pretty obvious you need much more to take Zouken out, but considering everything, Sakura might not even be dead either. Then again, weighty consequences, good writing, and all. Breaking this to Rin(and Illya) is another critical point to keep in mind.

Now that I think about it, it's not clear whether Shinji actually knows Sakura is dead either. So having a session with Rin where we just tell her everything to avoid her feeling played may not even be an option.
