Yeah, the Christina puking in the pit theory is a little far fetched, but I just don't think the producers would postpone a run due to faulty props. Maybe they would've postponed it for a minute, get the new pots set up, then resume. But I never ever believed that pots theory from Day 1. I always assumed Christina and James were too tired to do the run, or one of them got sick backstage before the temple run even started.
And yeah, Elise was pretty slow in the War Fan run. Maybe it would be a stretch to say the team would've won, but that production error never should've happened, period. It wasn't Jeremy or Elise's fault the Tomb door got stuck. I also agree with you about the Belshazzar kids. They really got robbed, and they were easily one of the, if not the, unluckiest teams on the show. Their temple layout was just like Blackbeard, only Katherine and Sean actually knew what they were doing. If they had say, Silver Saddle Horn's layout, they would've won that layout for sure.
