I felt that they made it as clear as they could that Mercury was the one to kil his Dad. After all, Cinder says that she and Emerald were watching the fight, and no other people seem to be mentioned or seen nearby.

Agreed on the fact that she's working for someone. The mysterious narrator? Dust shop guy? Who knows.

And that fight scene? Possibly my favourite yet.
