The pair had already taken several pot-shots at each other, before John James commented on her "weird looks" that she made during her time in the house.
Rachael said: "I didn't mean to come in here to rile your feathers." John James replied: "You couldn't rile my feathers even if you tried."
He also pointed out: "[Rachael will] struggle to find someone to bring [out] the best of [her]."
Rachael, possibly referring to Nathan, said: "I've given up searching, I think I've found that person." She further hinted that she didn't want her "boyfriend to be upset" about the massage.
Rachael added that she couldn't believe the Australian still held "a grudge" over her.
Eventually, Big Brother signalled the end to the reunion, as Rachael said: "Thank God."
She added: "I would say it was nice to see you again, but it's not," before saying: "I don't know what's the problem with you, John."
Big Brother repeated his command for John James to leave, before Rachael sarcastically said: "Why don't you just leave, and good luck babe. I wish you all the best." John James smirked and laughed to himself as he left, saying: "Take care now."
