He either won 37 or 39 thousand dollars in total. He came in second place so unfortunately he is off the show.
It's 21 thousand plus 13 thousand, plus 3 thousand for the first episode, and possible plus two thousand for the second one.
This is because the 3rd place contestant gets a 1000 dollar bonus to pay for the trip over there, the 2nd a 2000 dollar bonus, and the 3rd one a 3000 dollar bonus.
I'm not sure if they give him a bonus for each episode or just the first one.
Good job dad.
