This is set in the time Jadis is about to kill Aslan, you snuck after Aslan to see where he was headed, after watching Jadis and her goons practically torture Aslan, bonding him and cutting his mane off you cannot take it anymore, you burst out of the bushes, screaming at them to let Aslan go

Aslan looks at you with his golden gaze, his golden irises piercing into yours, he almost looks upset that you came after him, not wanting anything to happen to you
