[SPOILER] - A "lucas" question

[Maike]

After what RA has told us in the press office interview I would expect "Vaughn" to be responsible if Lucas gets into trouble in the course of this series and is accused of being a traitor. He may well be involved in the storyline that run through series nine (and be the main baddie?) and Lucas may well hide from MI5 that he is somehow connected to this person. But if the baddie is someone else Lucas can come out of it innocent, even as the hero (though not necessarily alive).
