Just because you're correct doesn't mean you're right.

Not much to say lol.

Scenario 1: Basically what happens to Shirou when he summons saber but different, and instead of archer fighting lancer it's saber and lancer, and lancer sees you, and you summon archer.

Scenario 2: morning after summoning him he's making breakfast.

Scenario 3: waiting around for something to happen

Scenario 4: teaching you how to fight.

Scenario 5: blank

Updated to add 3 other masters and their servants. There's only saber and shirou, illya and berserker, and soichirou and caster. I'm trying to keep the count reasonable so I'll shorten down the stuff I included for them so I can fit one or two more in.
