[Spoilers] Sir Harry Pearce

[Silktie]

In 8.7, Harry seems to be worrying that the job is costing him his humanity. When he talks to Ruth about her concerns that they are using the kid, he says to her that they need her there to remind them that they are working with humans, not objects, and that he specifically needed her to remind him of that. Then later, when he decides that they can't extract Dhillon and Ashok since they don't know what the second target is, he tries very hard to explain the reasons behind his decision to Ruth. It is only when she tells him that it is the right call that he begins to look at ease with his decision. He wouldn't have done that in previous seasons.
