In The Escape Artist there's an in reference to tea which I don't understand.
When acting as Liam Foyle's defence Maggie Gardner drinks some tea which he asks about.
Foyle: What tea is that?
In episode three Maggie discovers a gift in her apartment which contains tea. You then see her on the phone "freaking out" and saying
Maggie: There's no way he could have known!
However no more of this is made in the story, it's implied that Foyle is stalking her, it's implied that he's been in her house, Will Burton even warns her to be careful but the thread is dropped instantly towards the end of the final episode.
What is the reference to the tea and why include it if it had no impact on the story?
