Hobwstly, Heather vs Duncan finale could be really intresting. Just imagin in every season the main antagonis and the secondry antagonist making it to the finale:

Heather vs Duncan in TDI

Courtney vs Justin in TDA

Alejandro vs Blaineley in TDWT

Scott vs Jo in TDROTI

Mal vs Lightning in TDAS (In this scenerio Lightning is the only VV who never was finalists and Gwen was never antagonist so this is the only choice)

Scarlett vs Sugar in TDPI
