The attack planned for the UK is a bomb on a plane on its way in from Russia to Heathrow. As they investigate further, Ruth enters the interrogation room alone with Harry and Elena when she finally finds out how exactly Elena was turned by Harry. But she reveals that all along, it was her who was trying to turn Harry and that she was a spy before Harry had even met her. Ruth's view on him though is not tainted, instead it's strengthened, much to Elena's dismay. Elena then also informs Harry that she lied to him for almost 30 years, and that Sasha is not his son... but Ilya's, leaving both Harry and Ruth shocked.
