Calculus Funk by @Raven_Scarlett (Sierra .)

So Mark's the kind of person that cranks his music up as loud as his ears can handle and buries himself in calculus or trig when he's angry, bummed, or stressed. It's therapeutic, I guess. He's not above dabbling in algebra, either, or any sort of arithmetic, he just favours calc and trig.

So here he is, in one such stressed mood (a low-level panic attack, to be exact, but it's hard to tell with him :XD:) and Kent's not really pestering, just wondering what's up.
