Series 9 Episode 8 discussion

[HellsBells]

Just re watched this episode. It is so incredible sad, and I guess now I know that Lucas doesn't redeem himself in any way, makes the previous series so pointless. I understand the point that Tea Lady is making about RA other projects, but I loved the back story of Lucas the tortured, but loyal spy. He deserved a better ending or at least a chance to survive.
And if they can do this character assassination to Lucas, is any member of the Grid who you think they are?
