Hufflepuffs are such busybodies, sometimes. Yourself excluded.

I don't know if you can be certain they won't try to cause trouble for you again. We oughtn't be too careless, anyway, because we've seen where that's led before.

As for them having a distaste for the Protectorate, well, it's probably much easier and more manageable to find fault with someone standing right in front of you, I suppose.
