Good observation, and well said MrG. She definitely seems a bit nervous/contentious as most would in that situation. This is why i like her- she seems like a real "normal" person (and beautiful). That's what RLC is supposed to be all about.
They just don't seem the type of people to do that for nothing, or for a thrill. On another note, she's awfully concerned with cleanliness, she keeps wiping down her belongings surfaces. Maybe a nervous habit?
Something tells me this couple is trying to make a case for the next RLC couple. A tryout? It"s funny how we've never seen them before and all of a sudden... Like Isa and Marcelo.
