[Shun visibly tenses as he hears that, and his tone is somewhat bitter as he responds, still not looking at her.] They're not here to tell me what they want anymore. And I didn't say anything about sole responsibility. But even the people I've known to be able to take care of themselves or had other people watching over them have been taken away from me. So that's nothing but an empty platitude now.

[Granted, the logical reaction to that is to realise that being there isn't necessarily going to help anyone depending on the circumstances, but Shun doesn't tend to care for logic where his capabilities are involved.]
