Episode 6 Discussion

[Tea Lady]

I have just watched the episode again and there is one scene about 3/4 of the way through where Harry walks into the Grid and he is texting on his mobile phone. I dont think I have ever seen Harry text before. Then he talks to Ruth and Lucas. The next scene is Sarah in the flat. She is texting someone. Do you think they were trying to make it look like Harry and Sarah were texting each other?.....one to ponder
