Jonathan is in major medical trouble in the 15th episode of Season 3, "Resurrection."
Jonathan's heart problems, a result of taking on Kryptonian powers from Jor-El to stop Clark at the start of the season, worsen. He will need triple bypass surgery. However, a Smallville High student named Garrett Davis holds up the hospital to receive a liver for his brother Vince, who is experiencing liver failure. He wants Jonathan's liver! But Clark doesn't let it happen.
The end of the episode is most intriguing, when Dr. Lia Teng, a doctor working for Lionel Luthor, takes Vince's blood platelet and uses it as a sort of medicine to revive those who have already died, exposing the truth behind Adam's mysterious residence in the town.
