We Had A Bet

After Oliver's shock at Selena's revelation of her knowledge of his past deeds wore out, he was filled with mad anger as he drove back to the hotel.

How had Selena managed to know about the bet and the reason he joined the restaurant?

There was only one way Selena could have found out about the bet and about his purpose at her restaurant. Ken.

As much as he didn't want to believe it, he knew that Ken had to be the one who told her everything. There was no way Selena could have found out on her own.

The more he thought about it, the more it made sense that Ken could have done that to jeopardize his chances of winning the bet against him.

He would never forgive Ken if it turned out that he was the one who had exposed everything to Selena and ruined his chances with her, Oliver thought as he got out of his car and made his way into the hotel to go find Ken.
