MAYBE

Klaus explained to Michael everything that happened and everything he had to do to get the bundle of money to pay the bills, and Michael didn't understand half the story. 

Mission, princesses, vampires, blacksmithing contract? All this was too much for the average person to absorb in a short time. 

Still, the money was already in Klaus' account and this was concrete proof that what Klaus had said was true. 

The happiness the two of them were feeling was potentially unequaled in terms of relief. They had never felt this way before.

However, that was not all Klaus revealed to Michael that night in the car.
