Demi Burnettis definitelynotBlake Horstmann‘s biggest fan.

In a PEOPLE exclusive sneak peek from Monday’s episode ofBachelor in Paradise, some of the women discuss the “love pentagon” Blake has found himself in.

“He wants to have like, five pieces of cake and eat all of them,” says Demi while chatting with Tayshia Adams andCaelynn Miller-Keyes.

“I think that he’s being selfish, and it’s all very calculated,” says Demi. “I don’t think that’s character traits of a good person is being selfish and manipulating people’s feelings. I don’t think that he deserves the grace that he’s been given.”

“It’s the Blake love pentagon,” she adds.

And Tayshia is more than happy to remove herself from the drama. “I’d rather just wipe my hands clean and walk away and be like, ‘You know what, you can dig your own grave,’ ” she says.

Blake is then seen tripping and hitting a rock while catching a ball on the beach. “Karma,” Tayshia says as the women share a laugh.

“This is all the validation we needed,” quips Demi.

Blake found himself in hot water after he got caught in a love triangle with Kristina and Caelynn when it came out that he hadslept with them both on back-to-back nightsat the Stagecoach festival. During the two-night premiere ofParadise, Caelynn, 24, tearfully told cameras he’d called their night together a “mistake” and begged her to keep the tryst a secret.

As the scenes aired, Blake, 30, posted text messages that seemed todebunk her story, suggesting she sought him out for sex and was stressed about people finding out. He deleted the text screenshots later Tuesday night.

On Wednesday, Caelynnspoke out about the incident, taking ownership for her words on the show while clarifying that she and Blake had a relationship that went beyond “a one night stand at a music festival.”

“I was upset and I let my emotions control my words,” she wrote on Instagram. “However, I did not go on a show to ruin someone’s character.”

“This could’ve been over after last night’s episode, but since it’s now all over Instagram, I felt like it was imperative to share my truth,” she said. “We all have our own perception of how different situations unfold and there are many sides to this story. I hope that we can all move forward and support one another, rather than tear each other down.”
