So, who do you suspect Clem is talking to on the walkie-talkie for ep.4?
Personally, I think it's a bad guy manipulating her.
I'm not really sure what he's manipulating her for though.
Considering what was said by Charles (the homeless guy) about kids not really being kids in the current situation, and the fact that cannibalism has already been used as a plot point (I doubt TTG would retrace their footsteps), I'm thinking the guy may be some pervert or something.
TTG have shown that they're not afraid to 'go there'.
Then again, I may be wrong and it could be a genuine survivor who may be able to help the group.
