So apparently my photo inspired ~emibooger to draw what Seras's reaction to Pip returning as a vampire. I'm seriously flattered and you guys should check it out: [link]
Its something I've thought about quite a bit actually. I mean its possible he could just "regrow" his eye as a vampire, but he could also get a smokey vampire eye (similar to Seras's arm) which might have certain abilities his original eye didn't have. I just stuck with the eye patch for now though because it was supposed to be a "directly after the fact" picture.
