I'm actually really torn between Holmes and BB here. On the one hand Holmes could shut Cauldron down HARD and also show up Tattletale. On the other hand he can find out about the Grail Corruption. He'll still obey us but having the info out there at all is super risky and just asking for trouble later on. But BB is also a really fun sounding option. Hmmmmmm.
Sigh gonna go with the one that's calling to me even though it's risky. Unless someone can convince me otherwise.
[X] Ruler (Sherlock Holmes)
Also quick question, does this mean we get to decide to make this a Great Holy Grail War? Having a Ruler doesn't immediately mean it's one since the Third War in Apocrypha had Shirou as Ruler and it was a regular HGW, but do we get to decide to make it one now that we have one on hand?
Edit: Another question, when the Ruler actually gets here I'm assuming that means we're making a fighting escape from Cauldron. Which ruler is most likely to wreck shit on our way out? Possibly cause some Cauldron casualties. I'm assuming Holmes would absolutely own Number Man and I kinda wanna see that.
Edit 2: Also, even though she's way behind, my reasoning for not picking Joan is that she would definitely be against us come the climax. Whereas Holmes is a risk, Joan is a certain betrayal.
