Tetchō isn't used to visitors. The only people who come to see him are the scientists, and visits from them usually mean a bad time. Still, he's given up fighting it, so when another figure appears, he's more or less resigned to it.

Until he realizes... it's not one of the familiar faces. No, he thinks he'd remember someone who looks like this, the cunning curve of his eyes and his mouth. For a moment, Tetchō pulse rises - he can't tell if this is good, or bad.

Well, he's already faced the bad. What could be worse?

"If you don't know who I am, then you aren't allowed to be here." Tetchō doesn't answer, because who he is is no longer important. How did this person get in, if he's asking a question like that?

...Then again, he couldn't care less if this person is or isn't allowed in the highly-secured lab. It means nothing to him, after all.
