Relationship expert John Aiken stepped in to clarify, asking Cass why she has such strong opinions about Sara.

‘How would you know? Do you know me?’ Sara snapped back.

“You just played games,” Cass replied.

Sara hit back at her fellow bride again, but John, 53, jumped in again, saying, “Cassandra, I have to ask: What is it about Sara that gets under your skin?”

‘She’s just lying. She’s just fake. Everything that comes out of her mouth is fake. You’re just lying. Every time I talk to you, you’re just the nastiest person,” Cass said.

Sara continued her verbal abuse against Cass, accusing her of having a “vendetta” against her, despite the pair never “speaking two words outside of this conversation.”
