Mostly I think these were questions to be double-checked when Hydra's able to ask again, or when Horace has resupplied our Veritaserum.

We started with what sort of work they did as an Enforcer, meaning what tasks were they normally assigned.

Then we asked about family members and anyone else who needs protection if we accept their surrender or decide to put them to work.

Next were the interesting questions, or at least, the interesting answers. How many wizards (of any blood purity) did you kill in Voldemort's service? How many Muggles? How many people did you arrest or turn in, and what did you think or know would happen when you did?

And of course, the really important question, which is why did you decide to cut ties with MLE and join us now?
