It's probably more important that you know why they're trustworthy.

Though I suppose that's for Harry to tell you. Which I'm sure he has.

But anyway - I'm the one that Pansy chose to include. What would she know about Sally Anne and Hydra's choices? Unless they told her, which I suppose could be. I'm just surprised that either of them know enough about Lovegood or Bones to know how they really feel about certain things, is all. Unless what Remy is saying is true and Hydra really is a legilimens.
