Buzz: Uh…

[The boy moves on to the faucet in the bathroom and starts fiddling with it, watching the water go on and off, testing its temperature, etc.]

Buzz: D-Do you understand me?

Boy: Sin.

Buzz: Could you understand me this whole time?

[The boy moves on to the shower and turns it on and off.]

Boy: Jo.

Buzz: But you speak Modern Mage?

[The boy moves to the toilet and flushes it, watching carefully as the water swirls away.]

Boy: Yat is Modern Mage.
