Bonnie Sinclair (Sanchez) is a fan Charakter created by Giahna Pantano a comic artist (as far as i know) and represents a cold astrobiologist and geneticist in her little world. She is sadly not canon. Bonnible is intellectual equal to Rick Sanchez and could be a good answer to his mystery past, and is considered in her comics, to be the Mother of Beth Smith Rick Sanchez daughter, and consequently the Grandmother from Morty and Summer Smith. To see her Fanarts and some comics just google the name Bonnie Sinclair. It is worth looking at. Pls apology my poor englisch knowledge. Have fun.
