After Sarah is transported into the video game, she supposedly can't control her own movements, needing her friend Cowboy to do so through the game controller. But there are numerous times where she moves of her own volition, like at 18:16 when she says "the Space Witch" and abruptly decides to head in the opposite direction, or at 19:15 when she opts to step in front of Max Cloud to block him from entering the main deck.
