[Suddenly, it all makes sense to Kariya. He hasn't seen his other self in a while, but he certainly hasn't forgotten about him.]

You must have met the other me. That makes sense. He's from a different universe, where everything went differently than it did in mine. That's why we look so different. Things like that happen here sometimes. It can be confusing.

[The other Kariya had had more power, so he'd been able to control the worms.]

It's nice to meet you, Emiya Shirou. [The name isn't at all familiar to him. Kariya isn't exactly in the know when it comes to other magi or much of what was happening in the War.] You already know my name, so I won't introduce myself.
