ugh that's two filler episodes in a row. I hate how they do this with a show that has a 16 episode season. How they make something so short so plodding is beyond me.

But I suspect the campers (seeing left overs from survivors who've died off - like the Country Club episode last season - is one of the best parts of the show) were just survivors who died. Possibly by ambush, or one of them being bit and no telling anyone, etc.
