Back in Episode 15, “Last Shot,” Mina, along with AJ and Dr. Torres, treat Tyrone and Aaron, who need heart transplants. Aaron ends up getting the heart, but then has an enormous stroke which leaves him brain dead. Tyrone is given the heart, which made for an emotional episode. Mina and Dr. Torres grow closer (they go on a date!), which fans love. Mina also grows professionally, as she shows to form a real relationship with an elderly patient (Harold). As a young doctor, she was always scared of getting close to patients, but she’s clearly matured a lot.
