Ilan, Betty and Elia were 3 bullies waiting to happen. They ticked each others buttons to push the boundary further. I didn't see Marcel being any worse than other people on the show. Many of the cheftestants had something irritating or off about their behavior. It was a shame to see Ilan win that season, especially after the sabotage done to Marcel in the finale. I'm glad Marcel keeps getting up, dusting himself off, and going forward for another day.
Dale Talde was another hothead I didn't like. Dale had a bad attitude several times. He was so disrespectful to Michael Chiarello. It was one challenge so suck it up and do what Michael asked. Dale was inappropriate, IMO.
