Both the guys in the bar were shot in the head.good observation. Rick gave the fat guy three blasts. two to the chest and one to the face (I think). But the squirly dude from Philly, he only got one to the chest. I kept waiting for the squirly dude to reanimate as (I can't remember who) picked the gun up off the dead body.
Speaking about oddities. Anyone think slicing yourself with a knife to draw blood then using that same knife to kill zombies is a bad idea? Just sayin'
Everyone is infected. That's what CDC Doc whispered to Rick. He probably forgot with the enormity of killing his partner.
