Series 9 Rumours & Speculation

[Silktie]

If we are going to have a "Lucas as a traitor" storyline - and I'm not convinced of this at all - I don't think it's going to be for Russia. It's just not logical for them to have this storyline only two seasons after we had the exact same thing with Connie. So I'm thinking he could have been involved in something shady before being recruited by MI5 - but something criminal rather than traitorous. This would explain the flashbacks they're filming. Perhaps someone from that past (the ex-girlfriend mentioned?) tries to blackmail him into doing something treacherous, perhaps on behalf of the Chinese.
