I’ve given this idea some thought but why would grandpa take custody of a bi-racial baby? No way would he own up to paternity especially with grandma’s supposed” big bank job”. I think FMD is involved somehow.
A granpa love child could explain Stanley Ann's lack of a pregnancy and her wish to do her fathers bidding,also why zero all but ignores his supposed obama side of the family. I really don't know just guessing. Trying to put the pieces of the puzzle together.
