I think however anyone is portrayed in there you have to take with a pinch of salt as editing can completely change how someone comes across, the only thing you can take mainly on face value is what someone is saying, so Ty with the whole 'I miss the game', at that's honest.
The heart rate challenge - Jesus. Cringe central! Medhi and Sammy, yeesh, it was so awkward to watch - same with Mal - really uncomfortable viewing 
I think Leah is stunning - really beautiful and understated. I love Whitney - she deserves so much better than Medhi. 'You drain all my energy'?! He's so condescending and rude to her. She needs someone who is actually interested in her.
