User blog comment:ArtDraw12/TD Theories: Who May Return in Potential Future Seasons?/@comment-5231983-20160613225414/@comment-26910203-20160614025524

I still think Amy (either her or Topher but he seems like he'd fall more towards lovable idiot in the future) is our best bet for a main antagonist out of existing characters even if she hasn't been presented as the brightest bulb...there is some serious potential there, she has the looks, dirt on Samey and has shown small signs of manipulation. Not to mention she will have to fend for herself if she is on the opposite team as Samey which I suspect would happen if they both return (and would be a reality check).

Every season needs a Heather/Gwen, Sugar/Sky, Dancers/Cadets type conflict and Amy/Samey practically writes itself.
