Series 9 Rumours & Speculation

[Mrs. Jones]

I am new here and don't know if anyone had suggested this theory yet...what if Vaughn is working with Harry to expose Lucas as a double agent. If Lucas would have blown off Vaughn and not given him the Albany file he would have proven himself a trusted servant of MI-5. But now by giving into basically everything that Vaughn has asked for, Lucas is digging himself deeper and deeper into a rut of deceit.
Also if Malcom had cleared out of the apartment that Lucas had visited him in earlier--how could Malcom have done this without the aid of the agency?
So then why is Malcom seen as "explaining" to Harry how Lucas came to ask him for the file? Maybe it was a flashback to a conversation that Harry and Lucas had which resulted in the agency clearing out all of Malcom's things.
Also when Malcom called Lucas "John" when speaking to his mother, that was a nice touch...
