The Short Version:
Huck: "Oh hey Tom, I want to free that slave, Jim, over there."
Tom: "Jim? Oh he's free, it says so in Miss Watson's will."
Huck: "Oh okay, cool."
Huck: "Oh okay, cool."
The End.
The Ending Everyone Wanted:
After managing to ditch the Duke and the King at the graveyard, Huck and Jim continued along the river. The whole way they were laughing and enjoying themselves, having talks about superstition and what not. Overall enjoying one another's company.
They soon got to this town and decided to go get some supplies, they were in northern territory so Jim didn't have to pretend to be a slave. While they were heading over to the shop, Jim and Huck heard a voice call out to them.
"Jim!"
They looked to see a black woman followed by two black men walking over.
"Mama?" Jim replied, his voice shuddering.
They all gathered in for a big hug, tears rolled down Jim's face as he was happy to finally be with his family. Jim looked over to see Huck standing there watching and invited him to join in the hug. Huck figured he may as well since he didn't care if it was something looked down upon by society, so he walked over and joined their group hug. Jim was finally where he wanted to be.
The End.
