What they’re saying

“Sloan made his entrance onto Grey's back in Season 2 and he's a bit of a scoundrel. The former best friend of Derek shows up at Seattle Grace and flirts with Meredith, before being revealed as the person Addison had an affair with. While he's originally all ego and sex appeal, the character was ultimately an onion whose deeper feelings were methodically revealed throughout the course of his tenure on the show.”

“It turns out that he was actually in love with Addison, and wanted to be with her. Despite this, he was insistent that he'd find a way to repair his familial-like relationship with Derek. While he and Meredith might be in the Dirty Mistress Club, it soon became clear that he was much more than that. Eric Dane masterfully pivoted between these two sides of Mark, resulting in McSteamy becoming instantly popular among viewers.”
