How does it end?

Ok I hope i don't make it too confusing. they are ordered two take ten paces away from each other so they go to the denter of the dueling place and begin their paces. During that time Luke is trying to get Caleb to confese about what happened with Will and how it was an accident. On the tenth pace they turn to face each other and Luke drops his gun telling Caleb to just tell them the truth. Caleb can't shoot him so his dad grabs a gun and aims at Luke and Caleb shoots his dad. As everyone is crowding around his dad, Caleb takes another gun and walkes away. He puts the gun to his head and almost kills himself but Luke runs over and tackles him bringing the gun away from his head. He helps him up telling hi it will be ok. Then we see Luke and govenor are talking. The Governor is going to take over the Skulls in place of Mandrake and Luke decides to just leave. He takes the boat to an island where Chloe is waiting for him. they kiss and walk off and then the credits roll up. I'm sorry but I dont remember the conversation between Luke and the guy but i hoped that helped.
