There's a confused look on Ren's face for a solid few seconds... before she quickly shifts to recognition as her brain catches up with what Akechi's saying.

"One. One without glasses. Yeah. I met him. Before I ran into you."

She's also feeling awkward now. Wow. Uh. Social awkwardness and confusion sucks. What the heck did he think she implied? Same person-- A relationship? Oh, that's extremely awkward, oh crap.

"No, yeah, you should be a team."

There's a quiet beat as it finally clicks into place for Ren. This is what has been bothering Akechi. There's something going on with his Ren, and it must be weighing on him.

"...Why aren't you together-- I mean as a team then?"
