Firstly, I think Nasu is trying to kill me.

Having three figures from Greek myth in one war is just too much for my heart to handle.

I had some hunches for a while now, so having Archer finally spill that Caster is Medea made me happy beyond words. I'm definitely very curious how the final showdown will be handled, not only with her having both Saber partially broken and Archer on her side (though of course the latter I am figuring is a setup, but we'll see), but to see how they handle her at the end of things in general. Hercules' Fate sendoff I really enjoyed so I'm curious how Medea will be handled in that regard.
The graveyard scene was perfect for me too. I know I'm biased to begin with since of the heroines, Rin is easily best girl for me (though of course Illya is a close second), but I was rather impressed with how things played out. I might have mentioned before that I don't usually go looking for romance series and such. While there were parts of Saber's romance I did enjoy, I still didn't really feel it clicking with how I work mentally. While more than likely still in the beginning phase of Rin and Shirou (that confession at the Emiya household :')), I find their dynamic clicks in my brain a lot more since it's a relationship where both know the other won't budge from their position and instead they merely patch what may be broken in the other and buffer them. That's the sort of thing that makes my heart get all fuzzy.
