Judith Grimes
Judith Grimes is Lori's baby and Carl's sister, conceived with either Shane or Rick sometime in Season 1 and born in Season 3, episode 4 ("Killer Within"). Maggie delivers her via a crude Caesarian section, using Carl's knife, and Lori dies during childbirth. Daryl nicknames the baby "Li'l Asskicker", and Rick allows Carl to name her after his third grade teacher. Judith's fate is seemingly unknown following The Governor's final assault on the prison. Rick and Carl find Judith's empty car seat, stained heavily with blood, and presume her to be dead. However, it is revealed that Tyreese had rescued Judith before escaping from the prison with Lizzie and Mika; the three are walking through a forest, with Tyreese holding Judith in his arms, before they reunite with Carol.
