Could Randall's group be The Saviors?
We're now three seasons on and know that we can expect a new 'big bad' soon. Speculation that Negan might soon join the show is rife.
If Negan and the Saviors were to join the cast in Season 5, there's a chance they could be the same group that we met in Season 2. It does seem unusual that after they retreated from the bar shootout, we never heard from them again, and seeing that Randall went to school with Maggie Greene, it would be likely that the rest of the group stayed close to King County.
If Negan and the Saviors are set to appear in Season 5, wouldn't it be mind-blowing if the events of Season 2 came back to bite Rick, and acted as a catalyst to spark the war with Negan and his Saviors?
Like I said, it's just a theory, but it would be a great callback to earlier in The Walking Dead if turned out to be true.
