The heated exchange occurred after Harriet, having spoken to the Traitors, grew irate while discussing the twist, leading to a shouting match with Roxy.
Harriet has since apologised to Roxy for her behaviour, with Roxy acknowledging it was 'hard to watch' the raw emotion displayed.
Despite her unravelling and subsequent urging for others to vote for her, many viewers have praised Harriet as 'the best Faithful' for her earlier actions in the series.
