Would she have the ability to whisper when she's being brought back from dust?

[Wait, no, that's a bit of sidetracking. Leslie has other reasons to hope Drummond is killed, but the way he worded that makes her give one related to those worries.]

I don't want her to be whispering in anyone's ears. ...It's not that I don't trust Miss Nessie or anything like that! But I think, from what I've heard about her, anything Drummond knows should die with her. I can't think of what we don't already know that would be helpful to learn from her.
