So, Aaron stole money from the Mafia?
And he and Adam have been living in Italy together and keeping in contact with Cain?
Adam tells Cain what's happened so he goes and kidnaps him?
And as
@crazycakelady says, how did they get Aaron to the UK?
Did he have his passport on him when they kidnapped him?
Did he sit quietly while they brought him back?
Why are they tying up his hands? Couldn't they just hide him in a rented flat somewhere?
And why hasnt he cried yet?
