Wally works late nights. He's always afraid that he won't be able to protect his family (surprise surprise I'm a terrible person). Josephine is always worried about her husband's health and wants him to be awake and strong enough tomorrow to live (he hardly eats anything due to stress). One day while he's in the lab, at about 12:00 at night, Josephine comes in and the lets Wally listen to the baby.
"You hear that? That's your child's heartbeat. Your child is growing strong, Wally. I need you to be strong enough to see this child grow. Come back to bed, you nerd." She said to him. And Wally being the big sucker he is when he's tired, starts crying.
I'll probably fix this later Idk
