Taking Grandpa to the mall wasn’t supposed to be a life or death (and after death) situation. Thom Sheldon avoids visiting his aging father as much as he possibly can. Even now that Rick started taking a new experimental drug that seems to be helping his Alzheimer’s, it’s still an unpredictable and rarely pleasant errand. If Thom could avoid visiting his old man without getting guilt-tripped by his wife or hounded by his own conscience, he would. But today Thoms’ wife Carly and son Brendan are along for the ride, and there is no getting out of taking Rick to the mall. No one could have guessed that the zombie apocalypse would start near the food court. Except for Rick.
