Ever since the Saviors appeared on the show, the writers have provided a couple of alter egos to members of Team Family.
Characters that are paralleling each other and have actually a lot in common, despite the fact that they are on opposite sides. Characters that are alike, but had different paths and that could've easily ended where the other is right now, had they had a different path.
Each pair has confronted each other at some point on the show.
