Who gained heat on last night's SmackDown (February 6)?

Gained momentum: Bobby Roode, Rusev, and Randy Orton

Bobby Roode retained his United States Championship in a thrilling match with Rusev at the start of the show's second hour.

After the contest concluded, Randy Orton came and laid out Roode, Rusev, and Aiden English out with three RKOs. We don't know what the Viper's motivations are, but a U.S. title program is probably in the cards for WrestleMania. It's even remotely possible that Rusev could be involved in the angle.

Let's see where it goes.
