when does mark sloan come to grey s anatomy

You're a struggling young doctor, barely making ends meet with a measly $2000 monthly income. Life's pressures and trials weigh heavily upon you! But lo and behold! One fine morning, you wake up to find yourself equipped with some sort of cheat codes... You're scheduled for an appendectomy, so you roll up your sleeves and get ready to explore the abdominal terrain: You touch the cecum: "Cecum: Healthy!" You palpate the colon: "Colon: All clear!" You reach the appendix: "Appendix: It's an inflamed, pus-filled appendix monster, level 15, rare creature. Recommendation: Perform an appendectomy!" With a decisive hand, you wield your scalpel and skillfully remove the troublesome appendix. "Ding! Rare appendix monster eliminated! Rewards: +100 experience in appendectomy, +$100, and a shiny white suture needle!" And thus, your journey begins as an emergency surgeon. But remember, with great healing powers comes great responsibility!
