Apart from John spilling the old truth tea to Marc, what I noticed most is that he was really well-mannered to the staff in the "hotel" whereas the others acted mostly like pigs.

he was polite actually, marc asked him for his opinion and bang he got it....marc is the ultimate hypocritical control freak bully. he demands everyone speak their minds and when they do he has a tantrum and refuses to listen and talks over everyone...hes been throwing cheap insults and upsetting and bullying from minute 1

Remember, this is a guy who was ousted from his job because his colleagues couldn't handle his disgusting personality.
