I like Ross too BlueBelle he's a bit of a rogue but seemingly with a good heart underneath all that scalliness & I think his cheeky, irreverent wit lightens many a dull scene. Also, not too sure about the Ross/Laurel thing. She's a bit of a go-getter in a quiet way isn't she!
No real clue about the Jodie/Graham connection...is she a sleeper for MI5, is Graham her puppetmaster, what on Earth is the endgame and how long will it take to get there
Dr Todd makes my skin creep - good work to the actor who plays her. Isn't there a vacant bunker, recently evacuated by Mac, where she could cool her heels for a while and reflect on her heinous behaviour against Jacob (getting on my nerves a bit tbh) & Charity?
