(September 2012) </Td> </Tr> <P> The American Broadcasting Company (ABC) characterized Karev as "honest", "always tells it like it is", while also citing his mouth, his punctuality and him being a "smart - ass" as his weaknesses . Shonda Rhimes said of Karev: "I love that we have a character who can do something wonderful but still be a selfish cranky ass about it . Alex gets to be complex in ways most characters don't because even though he's got a moral code, his moral code is totally twisted and dark . But he's essentially good--deep down inside ." Carolina Paiz, one of the writers of the series, wrote: "He has so much going on inside...you think you've got him figured out but then he just reveals this whole other side to him ." </P> <P> "He is superficial sleazeball who turns out to be a nice guy and a talented doctor with an amazing bedside manner, as well as the budding love interest of Katherine Heigl's character Isobel ." DVD Verdict wrote of the character's development in the fourth season: "Love him, hate him, or both, Karev speaks his mind, rough edges and all . But ultimately his cold heart seems to be softened by his blossoming relationship with Jane Doe / Ava / Rebecca ." Rhimes felt that the 100th episode during which Karev marries Stevens showed how he had grown up: "Look at him . Standing at the altar and saying those vows like a man . (...) He's become a man who can step up . And I love him for it ." </P>
