Not the same group. There were only three guys at the house, Rick killed one that turned into a walker that I presume killed the remaining two.......
You could hear a guy screaming and a gunshot while Rick was taking off......
It’s the same group, or at least the silver haired guy Daryl decked was the dude on the front porch at the house where Rick & Karl were staying.
We don’t know how many people were with that group in the house with Rick. There were the two guys who fought over the bed, there was the guy who was sitting on the toilet who was killed by Rick, there was tennis ball guy, but we don’t know how many others might have been in the house.
