Emmerdale - Current Episode Discussion - III

[Son of Cain]

We saw Rose take the phone which was dialed to Kim and put it behind the pillow right before they started kissing and the rest happened offscreen.

So, I'd be really surprised if Kim doesn't know, and think she's already plotted out her next moves.

Why is it that when people are on the phone, and they do not want the person they are calling, to hear something they say to someone near them, they cover the phone with their hand, but when they want to record someone they put the phone in their pocket or in this case down the side of the sofa?
