The Vanish Pact / 𝘙𝘪𝘤𝘬 𝘎𝘳𝘪𝘮𝘦𝘴 (𝘊𝘙𝘔)

Cassandra Adams is scraping by as a consignment nurse while she protects the daughter she found just a few weeks after the world ended. During a crisis, it's revealed to Okafor that the cold and off-putting nurse in the consignment block is actually a capable fighter and former surgeon - an invaluable asset to the CRM.

After quickly realizing he's found a new A to recruit, Okafor blackmails her into becoming the lead doctor for the soldiers, requiring her to complete training as well, so that when the time requires, they have a fight-ready doctor to tend to the fallen.

Her first case? A butchered amputation with severe burns inflicted in the field.

A few months later, Cass is reintroduced to the stubborn Rick Grimes, insistent on escaping the institution to get back to his family, as they're put in the same training program.

Rick has a poor-healing amputation and Cass is the key to survival. Cass is struggling in hand-to-hand combat and has gotten nowhere in her escape attempts meanwhile Rick has gotten further than anyone else before him.

Despite their mutual dislike, the two agree on a deal- a pact.

She keeps him alive and he helps them vanish.
