I don't!!!
I believe that big brother wanted isaac as he is a character and well known on the reality scene.
Now i think that they was meant to go in as a couple.But isaac had things he could not get out of to do in America.So they stuck noirin in with the knowledge isaac was going in.
But i believe that after keneth went in the house noirin thought they would never put isaac in now and then decided to use siavash as a bed buddy for a cuddle.She made it clear there was nothing on the outside between her and siavash.
Plus made sure everyone knew she did'nt see him as bf material.
She has constantly talked about her ex and many times said she thinks she has blown it...well how can you blow it with a ex???I think they see how it was with rex last year and they was dead set on it happening again.They tried and failed with ken/karly so instead of learning by it they just do it again and again.
