Also known as: Cav Mals
Caroline Reznick, Morgan's mother and a famous painter, has multiple cerebral cavernous malformations causing progressive bleeding and seizures. The episode centers on the team's attempt to treat her with an experimental stereotactic laser ablation procedure to preserve both her life and artistic abilities, which she initially refuses due to fear of losing her creativity.
Oliver is given six months to live with a malignant peripheral nerve sheath tumor and spends the episode pursuing an extreme bucket list, including skydiving and eating fugu. His tumor unexpectedly shrinks after infections allow his immune system to recognize it, leading to a curative surgery option.
Also known as: Seizure
Caroline has a complex partial seizure while preparing food, causing her to cut off her own finger with an electric knife. The team debates whether the seizure was caused by her cavernous malformations or by gliosis from microbleeds, which influences treatment decisions.
Also known as: Severed finger
Caroline accidentally amputates her finger with an electric knife during a seizure, requiring emergency surgical reattachment.
Also known as: Sprained ankle
Oliver injures his foot during his first skydiving attempt as part of his bucket list activities before his expected death from cancer.
Also known as: Shingles
Oliver develops shingles due to immune suppression from his cancer treatment, initially mistaking his symptoms for fugu fish poisoning after eating potentially toxic fish.
Also known as: Fainting
Oliver experiences syncope and hits his head after eating fugu fish, which he attributes to poisoning but is actually related to his underlying condition or shingles infection.
