Brother vs. Brother

The brothers decide there's no rules on anything in this competition, and for the first challenge, they take on their living rooms and front entrances. Kendra Wilkinson and David Bromstad stop by to judge, and the winner gets an exclusive NASA reward.

Jonathan and Drew each renovate their kitchen and dining rooms but run into space and structure issues. Alex Guarnaschelli and Veronica Valencia stop by to judge the rooms, and the winner is awarded a romantic dinner from a famous Michelin chef.

The third challenge has the brothers renovating their main bedroom suites, and Drew thinks he's bitten off more than he can chew while Jonathan scrambles to keep up with him. Jasmine Roth guest judges, and the winner receives a very magical reward.

The Brothers battle it out in the Additional Dwelling Unit challenge and Jonathan pulls out all the stops in hopes of a victory. Breegan Jane and Trixie Mattel guest judge the spaces, and the loser is sent to play tour guide on an LA tourist bus.

Jonathan and Drew compete with multiple indoor spaces as they race to the big finale. Egypt Sherrod and Mike Jackson stop by to judge and award the winner with a once-in-a-lifetime chance to cruise in the car of their choice from the Petersen Auto Museum.

Jonathan and Drew's no-rules competition is almost complete as they look to renovate all the exterior spaces to create the best curb appeal before their homes go on the market; the brother that sells for the most profit will celebrate the victory.
