'Real World: Portland': Nia Punches Johnny In Brawl Preview (EXCLUSIVE VIDEO)

Remember the days when you could almost get kicked out of "The Real World" house for slapping somebody? If that's still the case, Nia might have to start packing.

In a preview clip from Wednesday night's "Real World: Portland" episode, Nia and Johnny get into a fight that escalates into an all-out brawl.

In this exclusive preview of Wednesday night's "Real World" episode, tensions start to rise when Nia wakes up Avery and Johnny by turning on the lights in their bedroom. The situation escalates when Nia gets possessive over Avery's dog Daisy. And it all goes to hell when Johnny puts a used tissue on Nia's back and then pours a cup of water on her. Nia responds by punching him in the head about 10 times.

The clip ends with Nia picking up a blow-dryer and following Johnny into another room, pledging to knock him out.

"It's like the easiest game for me, because I'm so manipulative and powerful. Like, I don't care about you, I'm gonna do whatever I want, and that just is what it is," Nia says.

MTV's official description for the episode reads: "Just when all seems to be heading in a better direction between Nia, Johnny, and Averey, Daisy gets in the middle and a huge brawl erupts. Anastasia’s dislike for Jessica comes to a head."

But Nia's not done throwing haymakers. MTV has been teasing footage of Nia sucker-punching Avery from behind since the season began, and it looks like that incident could follow this one.

See the brawl erupt on "The Real World: Portland," which airs Wednesday nights at 9 p.m. ET on MTV.
