I think his powers are suppressed due to some sort of spiritual chain. Obviously andels don't grow the say way humans do. And since Eden already exists in this timeline, then maybe Lilith is his mother. Lucifer said something about hoping Metatron was an okay sacrifice. So could it be that Lucifer and the kids mother could be in cohorts with each other, to sort of over take the throne of G**. And since Gabriel seems to be working with them (even tho in the bible it's the very opposite). Could it be the Gabriel is a spy, and since Michael is loved by g**, Lucifer is jealous....man I don't know, am just yapping here😞
