Tensions have risen in the 'Big Brother' house following this week's nominations.
Marcus and Siavash are facing eviction from the house on Friday night.
Siavash admitted to the other housemates that he hadn't nominated anyone again, and then became involved in a major argument with Charlie, Rodrigo and David.
Rodrigo said that Siavash did not nominate because he wanted to "look good", while David said that everything Siavash did was tactical.
In conversation with Charlie, Rodrigo claimed that Siavash was trying to appear as "the nice one" and that there was nothing nice about someone who would cheat on their girlfriend.
He also vowed not to speak to Siavash again.
