That's Gabe in the first panel and the rest of the page. I have an empty arrow next to his face that I meant to fill in with his name... but I forgot. 8D

When I drew this page, I was so impressed with myself for drawing Gabe's head at that angle. :V And no, that's not a real song playing. I think the reason Gabe's ringtone for Stefan is so annoying and weird is because Jo randomly changed it on Gabe just to annoy him. Hoho.

It's up to your interpretation to decide if that's armpit hair or weird shading on Gabe's armpit.
