I'm no lion trainer, but I'm thinking maybe you stop chasing it, hitting it, and spraying it with water and it will stop trying to eat you.

Luka: Nikolai!!! Help!!! The lion is trying to eat me and I am bleeding badly!!!


Nikolai: Don't panic, Luka! Just let your training take over. Just like we practiced. Chase it and hit it. I will spray it with water.
Luka: AAAAAAAAAGGGGGGHHHHHHHHH!!!!!!!

Nikolai: Okay, I thought that would work. Maybe we didn't use enough water.

Luka: AAAAAAAAAGGGGGGHHHHHHHHH!!!!!!!
