Summary
There’s no turning back. You’ve done what you’ve set out to do, with the stolen catalyst, the fossilized snake skin; you’ve made it this far and summoned the strongest of all Servants from the Throne. You’d do well to remind yourself of that, and remind him.
“Waver Velvet,” you announce, voice strong despite the nerves. Hand raised, to show him the command spells, proof of the contract between you. “I have called you to fight for me in the Holy Grail War, and you have answered.”
There. Gilgamesh has only to blame but himself.
