Garble and Cadence?

https://www.deviantart.com/art/Garble-and-Cadence-433292932 Just saw this fanart on deviantart, it was based on a @Gojira012 profile idea that Garble use to be Cadance's assistant similar to Spike use to be as a baby dragon. (https://gojira012.deviantart.com/art/MLP-profile-Garble-345391127 ). I don't know if that would be a reason for his antagonistic behavior but if Hasbro addressed his reformation at all, maybe this will be the inspiration for it. What do you think?
