The clock guy wear jeans and a t-shirt. He look quite different from the other characters and he's probably a kid.
And the theory suggested above that clock guy may be Arhys and Gabriel's younger brother is perfectly valid.

Edit : btw, the shadow may be suggesting he is big-headed (
), but I guess that what we see is the shadow of wireless headphones. Given the pic, he might be a teenager. OK, now I have a theory myself : Faythe looks also like a teenager. What if the love story was between her and Clock guy, a love story a la Romeo and Juliet amidst a war between two opposing factions? After all, JP is a fan of Shakespeare as shown in Pull Me Under, no?
