when does rose come in grey's anatomy
Grey's Anatomy The season four premiere introduces several new interns, to be trained under Meredith, Yang, Karev, Stevens, and eventually O'Malley.[b] Among them are Dr. Steve Mostow (Mark Saul) who continues to make appearances,[96] and Dr. Sadie Harris (Melissa George) who formed a friendship with Meredith while the two were in college.[145] Harris is fired in the fifth season, due to not actually having a medical degree, and departs the show immediately after.[105] Meredith and Shepherd's relationship reaches a toll, and the two separate, leading Shepherd to entertaining a relationship with Rose (Lauren Stamile), a nurse.[98] Rose appears frequently until season five, when Derek and Meredith decide to rekindle their flame.[102] Throughout the fifth season, Stevens experiences full-out hallucinations of Duquette,[103] signaling that she is ill,[146] and once she is lucid, he departs, marking his final appearance.[144] Following the announcement of her relationship with Robbins, Callie's father Carlos Torres (Hector Elizondo) initially contests his daughter's concurrence in homosexuality,[147] but eventually accepts it,[110] and he reappears several times throughout the series.[115]
