Who do you think had the biggest downfall in Hell’s Kitchen?

Definition of a HK downfall: A good chef becomes a bad chef cooking wise.

I think Melissa (S3) and Zach (S11) had the biggest downfalls in HK. Melissa went from saving Julia from nomination to sabotaging the blue team. You could also tell her downfall just by looking at her hair. Zach went from being one of the two survivors on the blue team opening night to lying to Chef about salmon and sabotaging Ray. Sebastian was right, Zacky really was Wacky.
