Relationships get messy on 'Bachelor in Paradise': 'It's total chaos here on the beach'

There must have been something in the water in Paradise, because multiple relationships and friendships were imploding on the beach Monday on Bachelor in Paradise.

Couples and relationships formed quickly at the start of the new season, and, up until this point, it has been fairly calm and chill. In fact, at the top of the episode, one contestant mentioned how everyone was practically married already. However, it was just the calm before the storm because, after a few new faces joined the beach, things began to get a little messy. Exactly how we like it.

The biggest fight of the night was between Demi Burnett and Mari Pepin, after the Bachelor in Paradise veteran decided to move in on Mari's man, Kenny Braasch.

To be fair, Mari told Kenny she wanted to keep her options open. Kenny didn't love the idea, but warned her he would do the same if that's what she wanted to do. Mari's biggest mistake was probably confiding in Demi, because after the Bachelor veteran learned Kenny was no longer on his leash, Demi decided to pounce.

"Uh, sorry, I'm going for your mans. It's my opportunity. That's what we're here for," said Demi, who later added, "Kenny's so sexy. I heard he likes to be naked. I like to be naked. I want to have some fun with that." Moments later, Demi pulled Kenny for a chat and laid it on thick, even exposing her nipple, before leaning in to make out with Kenny… right in front of Mari.

"I happened to look over and saw them making out," said Mari. "It just sucks. Like, Demi and I have been cool. She was, like, giving me advice, and then she turns around and does this, and I'm right there, like, watching."

Later, during a heated confrontation between the two women, Mari told Demi, "I just want to know what's going on. I feel betrayed, honestly. I feel betrayed. I'm hurt by you. Earlier today, I confided in you, and now you're turning around and doing all this, so I'm confused."

Demi could care less about Mari being mad at her, as she argued that everyone on the beach was there to date everyone. Demi shared, "I don't know if Mari needs a lesson of how Paradise works and how we're all supposed to be dating each other and figuring out, like, who we like the most, but I also think she needs a lesson in hypocrisy because Mari wants to have her cake and eat it too, and so she threw mine in the fire."

Meanwhile, on the other side of the beach, Aaron Clancy got zero warning that his partner, Tammy Ly, was about to make out with his archnemesis, Thomas Jacobs.

"Tammy's been displaying, you know, human trash bag behavior. She definitely played him, in my opinion," said Tre Cooper. To be continued how the ongoing battle between Aaron and Thomas plays out, but Bachelor Nation took to Twitter in shock over how messy the cast is, and also totally amused by the complete chaos.

Bachelor in Paradise airs Mondays and Tuesdays at 8 p.m. on ABC.
