Seth is laid-back & dumb (Ramsay calls him Forrest) but knows a lot about Gordon which is best displayed in the second episode when they were on the reward where he expressed his knowledge on Chef Ramsay.
Season 5 Edit
Honey ratatouille with lamb chops - Ramsay deemed this to be the worst he ever tasted with Seth inappropriately giggling when he said it. Ramsay then said he could make history on being the fastest exit in Hell's Kitchen history.
"Gordon and I will be like peas and carrots once again."
"He keeps calling me Forrest (as in Forrest Gump), I think it's a great name!"
