Based on the promo (yes, I know that's dangerous), I have a feeling Margie & Luke and Tammy & Victor are racing for 1st place.
Kisha & Jen and as we already know, Mark & Michael lose their passports and have to go back. From this, I say the brothers go out. Kisha & Jen either stay in due to a footrace, or the brothers never find their passports.
Thanks for the promo, puddin.
I also found out that Fox has an official YouTube channel so if you're a fan of Hell's Kitchen, I posted previews of tonight's episode in that thread.
