She hates this, she hates how she's planning on sneaking out like this behind Rider's back. But if she can get Caster on her own without Rider even needing to be involved when perhaps there's a chance of happiness without even needing to finish fighting for the grail. It's a fool's errand she knows that, but she still wants to try.

She'll still need help though...Luckily she already has made an ally in one of the other masters. Saber's to be precise and even though he seems to be something of a goofball who doesn't realise how serious this whole thing is he seems to be doing pretty well for himself in the grail war somehow. If she and he take on Caster together without Rider's help then they'll only have to take on each other.
