Lori Is a Todd and She's Jason's mother, Sheila Haywood is Jason's grandmother in this AU and Jason is not a redhead...his hair is black and his eyes are blue, Willis And Catherine Todd are Jason's aunt and uncle in this AU.
His father...
Well I got a better idea for it :)
Bruce Wayne slept with Lori when they were teenagers and broke up with her before she knew that she was pregnant with Bruce's baby...
She met Rick Grimes while being pregnant with Bruce's baby, months later...Jason Todd was born...
Yes Bruce is Jason's biological father in this AU but he didn't know...until he finds out through a blood test :)
Carl and Judith are Jason's half siblings :)
Rick legally adopted Jason as his own :)
Things changed when Philip Blake; a criminal under Carmine Falcone's payroll along with Joe Chill...who murdered Rick and Lori...
Carl and Judith were in Rick's Best friend Daryl Dixon's custody :)
Jason ran away after his mother and 'father' were killed.
Here's what Jason looks like:
Black hair with brown highlights
Blue eyes
