Just playing the devil's advocate. But remember the person Victor described as having a gash on their foot. (Or am I merging Pegs with someone, hmm.) What I'm saying with that is maybe he's infected in ways not that visible, eg: Tommy was infected without wounds. What if Pippen was forced to become infected? It would be an insidious move by the Mallers to force infect someone, and then get them to get inside the tower. :D
