Ok first I got to Apologize - Grand order is a special and will thus have at best 3 Episodes (going by the epilogue. )
I loved some of the alternate Servants, Medusa having a Blast with a Stone garden was the best.
Also if you ever wanted to Know what Stheno and Euryale are like in the Fate universe - Have fun you will find out as the latter will definitely appear.
I jsut kinda resent that they didn't use the opportunity to introduce more Death Apostels, although one of them is shown, but I seriously doubt anyone would recognize
As for Euryale I looked her Character Sheet on the type moon wiki up, and while I don't know anything concrete how she acts in the Game to the anime a very special stat of hers actually Equals Gilgamesh's namely Independent Action - Meaning she will likely do as she pleases the entire time and troll everyone. Important stats aside her stats are overall better than Gilgamesh's Archer Servant stats with any previously known Master.
Any bad stat she might have is however offset by a fucking
EX rank luck stat >>.
Note Saber managed to evade a certain kill blow with jut
B
Too bad this isn't going to be a weekly series.
