It's all a game.
Harry, Jade and Nick don't care for each other.
All want to take each other down.
First Jade wanted Nick and Harry to
openly hook up (knowing they wouldn't so Nick would look stupid which he did !)
Then there was the Harry Nick Jade Cristian 'love square'

Here's how I imagine it all...
After Jade and Cristian got "friendly", Nick saw a chance to break free from Jade.
Think Nick's idea was to make out he wasn't a "player" but Jade was !
So Nick tries to break free while sticking the boot in to Jade.
Jade said as long as Harry didn't mind the "parallelogram" (love square), Nick shouldn't.
And Marc weighs in too helping stop Nick break free from Jade.
Jade says: "I wouldn't go calling it off FOR Harry" (i.e. between Jade and Nick)
Nick (mishears?) says: "No I'm not gonna call it off WITH Harry"
Now what do we see ?...

Jade saying Harry is using Nick for airtime ! (rare mistake in a feast of superb gameplaying)
Nick thinks Harry should go !
Gameplaying tactics they use are often clever and funny (especially Jade !)
But often feels a bit contrived and painful to watch.
