I like Linc and Amelia together because the relationship has evolved naturally instead of feeling forced. To me, Jackson and Maggie, and Meredith and DeLuca, seem like forced couples. So do Contacts and HAOG. So did Callie and Penny (ugh). This relationship is believable. At first they get together for sex, and Linc is sweet on Amelia but she doesn't reciprocate. He's confident enough that he isn't too bothered and he continues gently pursuing her. By now, they are close friends. Perhaps the relationship will evolve into romance.
