Series 9 Rumours & Speculation

[Tulsky O Zavod]

I've seen some pictures of Lucas running away from the explosion unscathed, so I don't think our Lucas would have suffered from any sort of amnesia.
On the BBC site it says Lucas joined MI-5 in 1995, it would be interesting to know at what capacity he was at a when he was visiting the British Embassy in the same year.
If he had recently joined the service I don't think they would be sending him on missions outside the UK so soon. Perhaps he joins just after the scene in Dakar. Lucas may have been recruited there, just like when Adam recruited Jo after she helped MI-5. He could have been a hero and helped prevent the explosion becoming a bigger disaster.

Then again I like the idea of Lucas being a criminal mastermind, being party to the explosion and using it to his own advantage in gaining entry into MI-5.
