Derrick Kosinski & Scott Yager are joined by Devin Walker & Marie Roda.

Two of our Challenge Favorites, Devin Walker (@MTVDevinWalker) and Marie Roda (@Marie_TBD) are the latest to join Ex on the Beach. When they were announced as cast-members for this current season, Challenge Maniacs were elated, but also a tad confused. What makes these two Exes? Derrick (@DerrickMTV) and Scott (@SHOTOFYAGER) are here to find out and to put their "love" to the test! PLUS, we are joined by another SURPRISE GUEST from their season of Ex on the Beach!
