[spoilers] Sir Harry Pearce 2.0

[Silktie]

Harry's different reactions might also be a matter of time. When he speaks to Adam, he's had time to mentally work through the implications and control/suppress his emotions on the subject. When Ruth confronts him with it, he hasn't had time to do it and his emotions and doubts over the issue show through. It's also interesting that when Danny raises concerns about Adam's stability, Harry quickly agrees to be the one to make the call on whether to involve the daughter. To me this shows that using her remains a sore point for Harry and he wants to make sure she is not unnecessarily dragged into this mess.
