Kotetsu fights Bianca, but I can't tell if its before or after Ash's battle with Stephan and Kotetsu. If its before Stephan, than Kotetsu beats Bianca and battles Ash later, but we know Ash beats Stephan leaving Virgil for the possible winner or possible person to beat Ash and then lose to someone else.
If Kotetsu vs Bianca is after Ash and Kotetsu then Kotetsu beats Ash so Ash loses earlier in the Unova Conference than before. So either Ash gets knocked out early or Bianca does. If Bianca loses to Kotetsu and Ash faces off against the four Download Rivals, that explains why they are downloads.
