You're not seeing double! Bad boy Dario, from Are You the One?, brings along his twin brother, Raphy, to show they can win Challenges as well as hearts. These two boys from Boston make a strong entrance flexing their biceps and their skills in the Challenge. Determined not to let the veterans control the game, this devious duo threatens to be twice as difficult to eliminate. Dario warns, "If someone gets on my brother's case, you're getting on my case. You got one problem with him, you got two problems. You don't mess with the twins!" However, when an unpredictable Challenge vet swoons for Dario, he sees an opportunity to woo his way to a win, but it could ultimately send the brothers packing.
