OH OH JO JO I DON'T KNOW KNOW
Both deserve to stay and both deserve to go go go.
Roberto - only creates tension when the subject is food - otherwise boring.
Roberto is I think a genuinely nice person.
Derek - will create tension about anything and everything.
Derek I think is a genuinely nasty person.
In the real world, I like nice people but hate nasty people. But this is not the real world and it should be judged merely on entertainment value. I think nastiness and tension can be entertaining if not overdone.
So I have to go with keeping Derek in. Roberto is too nice normally (out of food arguements) and does not have much entertainment value for me. Derek is a snidey b'stard and will be a bitch to anyone given the chance. Plus the fact for the second week in a row he has stressed his desire to leave. If he wants to leave then make him suffer and let him stay
