Kion was walking through the Pride Lands when he heard a growl. He searched for the source and saw Zira growling at Kiara. It looked like Zira was going to attack Kiara by the river so he got down low and moved closer. He got a better view of what was going to happen, he was Zira's claws unsheathed and his sister was scared and he didn't see any signs of his family. It was his job to protect the Circle of Life and he couldn't just let Zira attack his sister. He saw Zira's paw raised and he acted immediately by lunging and shoving Kiara out of the way, unfortunately, he didn't get out of the way in time and Zira's claws made contact with Kion's back left leg. Kion winced as he landed on the ground.
Kiara: KION!
Kion: Go! Now!
Kiara: Not without you.
Kion: I'll be fine, just go.
Kiara obeyed and went to tell their parents. She ran towards Pride Rock.
Kiara: MOM! DAD!
Simba: Kiara? What's wrong?
Kiara: It's Kion. He's facing off against Zira by the river. He-He got me out of the way in time before she struck but now his back left leg.
Nala: Kiara. Stay here. We'll go get Kion.
Nala and Simba took off immediately toward the river.
*Meanwhile*
Kion stood up to face Zira after he saw Kiara run off, possibly to get help. Kion growled at Zira.
Kion: How many times do me and my dad have to say you're not welcome here?
Zira: I will always come back to revenge my beloved Scar.
Kion: Yuck. Scar was never the true King!
Zira: How dare you?!
Zira lunged at Kion and unfortunately due to injury, his movements were slow. But he dodged barely in time. Zira's claws made contact towards Kion's left eye. He closed it immediately but it stung. He stumbled toward the river and was now hanging on.
Simba and Nala: KION!
Zira: Simba. Nala. Nice that you're here to witness your son's death.
Simba: NO!
Simba immediately went after Zira while Nala went towards Kion. Kion's eyes were wide with fear as he started to lose his grip. Zira thought quickly and removed Kion's grip swiftly as he fell into the river though it wasn't a bad drop, the water was rushing and wasn't safe. Both knew they had lost Kion and Simba snarled at Zira.
Simba: GET OUT NOW!
Zira: I think I caused enough pain for now.
Zira left and the 2 royals went back to Pride Rock. They broke the news of the Prince's death and everyone was upset, mostly Kiara. They all had tried to get to sleep that night.
