Thunderbolt was back for more revenge! But this time he had a clever plan...
  "Hello Spear-it.   Oh,  And son, Lightning." Thunderbolt mocked.
  "What do you want." Spirit asked.
"Oh?, Just another duel!" Thunderbolt replied.
   "I don't want to duel you!...." Spirit almost finished when...

  Lightning interrupted.
"Dad! I can totally beat him!"
  "I don't think you should..." Spirit cautioned. But Thunderbolt interrupted.  
  "Let him fight me! I want to see his strength."
"Yeah Dad! I can do it!"
 "If you win I'll never challenge you ever again. Oh, Just one little detail... If I win I get to STAY! And you Must leave!"
 "No Way!" Spirit said.
"DEAL! I'll Fight you!" Lightning said
   "Son NO!!!!"
But lightning ignored his wise father.

They Lined up for WAR!!!!! Spirit tried to get his son to stop, But it was too late... They began the fight.

Lightning was defeated. "Don't go anywhere son I'll Fight him, and avenge you!" Spirit said.
  "No Dad. I made a deal. I'm not breaking it!" Lightning said. "If I break my deal, I'll be a coward, and a fool. No one in the herd will respect me like they used to. I MUST leave! Someday I will return. And I will Be wiser and stronger. Then I will be ready to lead the herd.
As A STALLION!"
Then lightning wondered off. And Thunderbolt stayed.

(Side Note: Spirit is still the leader. It's just that thunderbolt gets to stay.)
