[Another sigh, this one more exasperated.] That's what I'd like to know. Since I can't give you that answer, the best I can do is explain how we encountered them.

[At least it's fresh in her memory, since it was the very dream she had today. Rin intuitively skips over certain details and focuses on the basics.]

Emiya-kun and I were intending to strike an alliance with Illyasviel von Einzbern, but by the time we made it through the forest, it was obvious a battle was going on. We snuck into the castle just in time to see her Berserker facing off against a Servant we hadn't seen before.

It was an intense fight, but Goldie bested Berserker in the end by exhausting all twelve of his lives. Strangely, his defeat didn't seem to be their main goal, though. After he was killed and Illya was likewise dead, Goldie tore out her heart.

Even though he's with Shinji, he's obviously the one calling the shots. Shinji wanted to fight us, but Goldie determined to leave because he was more concerned with preserving Illya's heart.
