(S05E10) "You go down the street and take a left at Jesus." - street directions to find the solution to a challenge

At first I thought this was the season finale of The Mole. Then I found out that it's actually next week where we found out who the Mole is and who wins the money. According to the preview for next week, we'll also have a reunion of the executed players and we'll find out how the Mole sabotaged the game and what clues the show laid out for us. The latter sounds great, but a reunion? I can't remember what the finales for the first two seasons of The Mole were like (the ones hosted by Anderson Cooper), but did they have a reunion finale too? If I remember correctly, the game didn't end on a test and we found out who did best and who won the money, it was actually another challenge that revealed the winner and the Mole (I think one finale challenge had them opening various doors to see who was behind it, or something like that?).

Anyway, let's get to what happened in this episode.
