3. The acting home secretary is a villain, right?

We thought Mike Travis (Vincent Franklin) was hardworking and trustworthy. But it turns out he might be another power-crazed mastermind, who potentially set up Julia’s death to stop her from becoming PM.

In last night’s episode, we saw special advisor Rob McDonald telling Mike that “it wasn’t even my idea” – suggesting that whatever “it” is may have been the acting home secretary’s idea. Was McDonald, who we thought was implicated last week, one of the red herrings Mercurio has confessed to including in the script?

4. Who put the blanks in David’s gun?

The scene in David’s flat that saw him attempt to take his own life was genuinely upsetting, and the sign of a very troubled mind.
