Real Sacrifice in a Fake Apocalypse

Summary

To save my mother who's been bitten by a zombie, I exchange my own kidney for the only vial of serum that's available.

I'm not given any anesthetic during the surgery. I bite down on a wooden rod until it snaps, but I still don't make a single sound.

But when I rush back to the shelter to look for Mom, I catch her talking to someone on the phone.

"You should drop the act soon, Mrs. Sawyer. Mr. Sawyer is going to collapse if this continues!"

I recognize the voice. It belongs to Mom's assistant, Richard Peterson.
