In the clip, Karolina's eyes are wide and mouth agape as she furiously exclaims at the table: "Oh my god you really are saying it!"
Lyn, who we guess said the offensive word, says in a voice-over: "It came out of my mouth before I even thought about it."
In the clip, Lyn wipes away tears from her eyes and says sincerely: "I really am sorry," to which Karolina fires back, "If you're saying will I accept your apology... No!"
It looks like things are heating up, but the big question is - what is the word?!
