"Glad to see that you don't wish to die just yet, goblin. Now, as to my insurance..."
Weston began chanting in an ancient, primordial language, moving his hands above the goblin's head the entire time. Finally, he tapped the goblin gently with his new staff and switched back to Common.
"I have placed my mark on you, goblin. With but a single special word, I can stop your heart and kill you in an instant. However, a different word can dispel the mark and leave you free. If you are loyal and amend your ways, I will release you. If you betray us, you will die. Sounds simple enough, right?"
(18 vs 4) The goblin believes you.
Symon takes his share of the gold.
"That's fine. I might make use of the bedroll, unless Symon wants to hit things even harder then he already does. Though... it might need to be cleaned first."
"N-no. I'm f-fine. You can have it..." Symon goes and takes a look outside. "It's g-getting close to n-noon. Are we g-going to eat here?"
You grab the bedroll and Symon, I assume, takes the backpack.
Everyone runs back to the wagon to see its still perfectly fine and all its cargo is still on board.
Go back to the wagon with the loot, bringing along the goblin.
"Say, Goblin. Does somebody of your kind have a name? Me? You can call me Chief."
"Cheif eh? You can coll me Grot. Wha' abou' da rest of ya fellas? Wha' do I call dem?"
He sees the wagon and hops on the driver's seat. "Well... I neva done dis befo'. I betta learn quick den." He then mumbles about at least being able to see over the horse. Assuming you all start to move, everyone spends two healing surges and heal half of your hp back up. NAdarr is out of healing surges. Everyone is back to full HP.
You continue on to the capital without a hassle, and the goblin indeed learns quickly about the way to drive a carriage.
You all arrive in the capital, but some people give a few dirty looks to your new friend. They don't really do much but frown however. What does the party do now? It is ~2:43pm. You have time to make a few rounds about town grabbing some gear quickly (no haggling) before heading out for another good distance before it gets dark. OR you can spend the rest of the day shopping, exploring the town and rest up at the inn. You all arrive in the trade district.
