Wes develops sepsis from an infected cactus wound in his upper right arm. The infection spreads rapidly due to his underlying liver and kidney damage from hepatitis C and past drug use, leading to multiple organ complications throughout the episode.
Also known as: Heart valve infection
The septic infection spreads to Wes's heart, damaging his aortic valve and creating a fistula. He requires emergency surgery with pericardial patch repair of the valve defect.

Also known as: Liver inflammation
Wes has underlying hepatitis C from his past IV drug use, which contributed to his liver and kidney damage and made him more vulnerable to the rapid spread of infection.
