Following on from their earlier heart-to-heart, Shabby said that Caoimhe was too harsh to Sunshine during their argument on Friday.
"The thing is I will stand with you in any argument…but there have been a few things you’ve said to Sunshine and I think ‘babe really?’," Shabby said. "You're spiteful for the sake of being spiteful to her."
Caoimhe claimed that she is only aggressive towards Sunshine because she puts on an act, which Shabby stressed is a way of protecting herself.
"She acts like an immature little child in here… the things she said the other day disgusted me. Her morals are completely different to mine, completely spoilt," Caoimhe said.
John James, who was in the kitchen at the time, weighed in that he used to agree with Shabby but now gets annoyed by Sunshine's attention-seeking. Caoimhe said that some of Sunshine's antics, such as her dance routines and her crying session after housemates teased her about her nose, make her "skin crawl".
The pair then disagreed on their opinions of Mario and Ben, with Shabby claiming that she doesn't trust them and despite making an effort to talk to them more, she doesn't consider them to be her "kind of people".
"I’ve opened the door [to them] a little bit but I'm keeping the security chain on," she said.
Caoimhe said that she likes both Mario and Ben and can see a lot of herself in the latter. She told Shabby that she needs to cast aside her previous disagreements with the 30-year-old writer and broadcaster and start afresh.
The pair clashed again after Caoimhe admitted to being angered by Corin's overly enthusiastic, happy-go-lucky attitude.
"I don’t like the people who do the whole, ‘You alright babe?’ constantly, constantly," she claimed.
"But you do it to me all the time," argued Shabby.
Caoimhe and Shabby later agreed that they are having trouble reading each other recently, but are pleased that they had shared and discussed their concerns.
