Hi everyone - good discussion here.

I just have to ask... would the Wizengamot simply take Dumbledore's word that Snape was trully remorseful?

I think that Dumbledore would believe Snape's story, and he wouldn't need an Unbreakable Vow to feel more assured.

I think there must be at least one other person, besides Dumbledore and Snape, who knows the specific details of why/how Snape definately changed his ways. Any court of law would require some proof, wouldn't they?
