This edit was inspired by one of Cheetahpaw's suggestions and some AU art on Friends to the End

It gave me an idea to my version of a Friends to the End AU:

Kion and Fuli fight and Kion nearly kills Fuli, but Beshte knocks him away. Everyone sees Fuli lying on the ground in a dead-like state and they believed that Kion had killed her. Bunga lashes out at Kion for losing control and killing their friend when she was only trying to help him. Kion snaps out of his rage and realizes what he had done, he then fears that he'll kill the others. Heartbroken and ashamed of himself, Kion softly apologizes to Fuli and his friends, then quickly runs off. The Guard was about to go after him, but then Fuli regains conscience. She sees Kion leave and she follows him (well more like limps after him). The Guard follow her, and they soon find Kion sobbing near a tunnel. Kion sees Fuli and thought he was seeing her spirit, thinking that she was coming to punish him. He fearfully runs into the tunnels, Fuli tries to follow him but then the tunnels' entrance collapses, trapping Kion inside. Kion doesn't know what to do anymore and is filled with guilt, grief, shame, and hopelessness, he eventually decides to just give up and let death take him when the time comes, believing that he'll join Scar in Hell for his actions and be forever known as one of the Evil Lions of the Past.

How can I just go through knowing what I had to do,
Meant the death of someone just to keep her mute
I should have known my place, she could have made the change,
She's going to die up there
I tore away her breathing space
All I ever wanted was to be something more
I know that I am wicked straight to the core
I left her bleeding out on that stream shore
My family, my friends, the Guard, it's all I lived for...

Stuck alone, swallowing shadows...
All bloody, minds flooded...
Tied...
To a history of shame...
Do my actions matter where they come from?
Or is it something that I should be numb from?

All I ever wanted was to be something more,
But now I know that I am wicked straight to the core
I left her bleeding out on that stream shore
My family, my friends, the Guard, it's all I lived for...
Its all I lived for...
Its all I lived for...
Now I've got nothing to live for...
