Turn 11: Garchomp is behind a Substitute, tries to attack while confused, but instead hits herself. The VS. Player believes this causes the Substitute to fade when in fact it doesn't. This ends up thinking that turn 13 ended with Latios hitting Garchomp herself when in fact it hits the Sub. In other words, Garchomp wins, not Latios.
Edit: oh, Hozu reported already. So I guess this can be disregarded.
