Tatsumi leaned back in his chair, taking a long, shaky breath . He had no idea Watari did that in his lab. (He'd dock Watari's pay for doing it on the clock, but that would give him away. And he didn't want Watari to stop, exactly...)
On the computer screen, Watari was a step ahead of Tatsumi, already zipping up. "It's too bad Tatsumi doesn't know..." he murmured, eyes lowered.
Tatsumi leaned forward, intrigued.
"...That I put one of those little cameras in that new mouse I gave him, too."
Tatsumi fell out of his chair as Watari winked and waved.
