Thomas and the other magic fighters were watching their senior teammates graduate and out of frustration from losing the battle months ago, Thomas had used his fire powers and ripped an actual hole in the fabric of reality.
Wyatt had noticed along with the others as Wyatt's appearance changed to his magic fighter outfit and used his powers.
"It… appears that this is a false reality"
Soon everyone's outfits had glitched to their magic fighter outfits and everyone had systematically broken this reality down to just nothing but a white screen.
Soon enough this white screen the team of 14 were in had started to break the more they used their elemental powers to break it before eventually it shattered like glass.
