It wouldn't surprise me though. At one point last night, she was holding the waist pack like you would a football. It wasn't on her waist, and I remember thinking that is a good way to lose that pack.
Like you said though... they seem too obvious.
I'm surprised nobody has talked about the poker players yet. They cracked me up last night. During the "Child's Play" challenge, I loved how the taller one had her bag on the base of the wagon and was pulling/pushing the thing all by herself while her partner had the exhausting job of carrying the balloons and kept telling her to go faster. The one time they showed the shorter one pushing the thing, they also show her yelling, "Help me!!" When they get in the cab, the taller one mentions she feels faint and the other one says nothing.
