Spoiler for UBW Spoilers:

In the UBW scenario, Caster is the main enemy. Caster already killed Rider, and she managed to RuleBreak Saber and kidnap her. Archer turns against Rin and joins Caster's group. When Rin and Shirou try to get help from Ilya and Berserker, they find out that Gilgamesh already killed both of them. With Caster now in control of Assassin, Saber, and Archer (and with both Berserker and Rider dead), Kotomine thinks that she has become too powerful and sends Lancer to help out Rin and Shirou. Archer then turns against Caster and cooperates with Gilgamesh and Kotomine, kidnapping Rin in the process. He sends her over to Kotomine who will use her as a container for the Holy Grail, while Archer himself will fight Shirou one on one. Lancer sacrifices himself to kill Kotomine so that Rin could live.

While that is a pretty good idea, you're so horribly off the mark it's not even funny. :X
