Any ideas on where Aaron came from?
Between my partner and I we've come up with these two suggestions:
1) He is/was a part of Terminus and is secretly looking for revenge. There was some talk about the group being larger, and more spread out, than expected.
2) He is a part of that group that Rick, Hershel and Glen ran into back in the bar when they still had Hershel's farm, finally caught up with them and wanting revenge.
There IS the possibility that he's a "genuine nice guy", but he has the signal flare to communicate with somebody. He's a little TOO clean to be on the road like them. Where did he get all that water from...... If that was his/his group's water supply he wouldn't have done anything to it, but he would likely expect that Rick & co would be too cautious to take it anyway. If he's part of 1) they are paranoid enough to assume everybody else is also, and if he's part of 2) he would already suspect Rick's paranoia.
Another thought to consider, there are those marks that were being left on the trees (the ones Morgan was following). Is that possibly a 3rd group out there, one as yet unknown? In any case Aaron knew Rick by name so the group must have been watching for some time..... But he didn't seem to know anybody else's name in the group, or at least he use them. Is he with Morgan and they are trying to join up?????
Yeah, I know..... a whole lot of conjecture off of just a small bit of a scene from the previews of what's coming next week. But isn't that the reason they offer those little previews, to get people speculating?
Any other thoughts?
