You people sound like you've never met someone who is bi-sexual before. They are out there, Nick seems to be one of them. He apparently likes both guys and girls. I think his flirting with Danielle is sincere, he said so in the diary room at least. Apparently he likes guys too, the hamsters cant hide who they really are forever. Being locked up in a house with cameras on you 24/7 all your little secrets can sneak out. We'll see how CBS chooses to handle the storyline...do they EXPOSE him or just duck it and leave the story to the live feed crowd.
