Ezekiel has been in the world of The Walking Dead since season 7 where he was the leader of the Kingdom. He has fought along side the group versus Negan, The Whisperers, and now is inside The Commonwealth. Since season 10 episode 5, it is revealed that Ezekiel has cancer. He is suffering from thyroid cancer. He tells this to the Alexandra doctor, Siddiq.. Ezekiel is not afraid by it. His grandmother was able to get through it. Siddiq tells him that he can survive but it almost impossible since they are in an apocalypse. His survival status is dependent upon getting the medical treatment that he needs to fight the cancer and stay alive. However, not all hope is lost. A storyline inside of The Commonwealth in season 11 is setting up a way that Ezekiel can survive his thyroid cancer and get the proper medical treatment he needs.
The key to Ezekiel’s survival is Yumiko’s brother Tomi. Tomi is Yumiko’s long lost brother that she reunited with at The Commonwealth in season 11 episode 5. Tomi is a baker inside of the walls but before the “fall”, he was a thoracic surgeon. He should have what it takes to remove the tumor on Ezekiel’s neck. However, Tomi wants to keep this a secret to The Commonwealth because he is happy just being an ordinary guy, baking cakes. He is shown in episode 6 to be taken away by Commonwealth guards, so people are predicting that Yumiko might have told someone that he is a surgeon. If this is true, Tomi would have to work as a doctor, instead of a baker.
I am not saying that this is a 100% sure way that Ezekiel can survive and get through his cancer, but this is the best chance that he has. It’s most likely not a coincidence that The Walking Dead is bringing in a surgeon as a recurring character just when Ezekiel needs one. The group needs to convince Tomi to go become a surgeon because Tomi has no interest in resuming his medical practices. Getting him to change his mind may be a task that takes time. However, I expect Tomi to change his mind and to save Ezekiel’s life by episode 16, thus Ezekiel will survive all the way to the end of the series!
