After hearing what the second years demanded from Arthur, to join them, his friends couldn't stay still.
They wanted to help him escape until Myla decided to handle it. Without their knowledge, she summoned her calamitous and shaped it into an orb.
With all their attention on Arthur, she controlled her orb moving at the fastest speed possible hitting the student near Blake first that he staggered with his steps.
It hit the student opposite him next on the arm as it left minor injuries. By this time, the other students were now stepping back in worry of it.
Some even pushed each other that the student near Brennon tripped, pushing him into the portal!
Arthur had already learnt of his friends' plan to save him and was complying with it during the commotion but before he could vanish, he witnessed Brennon being pushed into the portal.
"Brennon!" He also followed. He had to save him after all he was his guardian and his friend.
