Things are not good between Neal and Peter after last week’s blowup and it looks like the summer finale is only going to increase the tension between the two. 

In the September 18 episode, “Vested Interest”, Peter and Neal attend an FBI conference where someone is trying to steal high valued defense technology. They soon discover the thief’s brazen plan to take something much more valuable from the FBI. Check out the clip below to see Neal and Peter explaining how their partnership began.

White Collar will air its summer finale Tuesday at 9:00 p.m. EST on the USA Network.
