Ive gone down to the Rataway in Riften and found Esborn to take him back to Riverwood..
Now i ran off quickly to get back to Riverwood to finish the quest.. But now he's not following????????
Can anyone help me what i need to do? Anyone had this problem?
Ive gone back to the Rataway to see if he's being a slow [censored] but he's nowhere to be found

Who the heck is Esborn? Is he some sort of new character we haven't seen before?!

You've gotta stick by him at all times, or you risk him getting an arrow in the knee. Other than that, I don't know how to help you.

It's ESBERN.

Can't find Esborn? Ask Esbern- he might know...

When you first met Esbern, he will follow you unless you spoke to him whereby an option will make him run off immediately to Riverwood and you're suppose to follow him. Well he's essential so he can't die. Try entering the inn at Riverwood to see if he's already there.

should've taken the carriage.
