Unnamed Savior on Cover
Could he be Holly's killer? I mean judging from the shadow on Issue 117 it appears that he may be the one casting it. Anyone else get the vibe that he may come close to killing her before being stopped by Paul or perhaps after the Savior kills her (his forearms appear to have blood on them).
I thought that he killed (Or at least tried to) Holly, too. Your theory is pretty good, Drummer.
Could be tattoos, but the way it looks to me resembles more like blood than a tattoo.
