Andrew Francis (The voice behind Shining Armor and Braeburn) was recently interviewed over on the Trevor Devall voiceprint show. It is a long one, clocking in at a whopping hour and four minutes, and not pony focused, but there are a few neat tidbits in there regardless! I wonder if we will see more Shining Armor in season 3?
Check out the interview here! If you want pony specific sections, hit up 4:00 and 55:00 for the more in depth questions about it.
