I've never disliked Maggie, but she's NOT a strong enough character to hold my interest for an entire episode.
I usually* like Jackson because he is pretty consistent about setting boundaries, which are sorely needed on this show. His "I'm talking . . . to someone else" was a perfect example.
*Except during this breakup. There's a lot of manufactured anger on both sides. She's single, so he shouldn't be jealous. He's with someone new, so he should be happy. Maggie's decided her true love is surgery, so she should also be un-jealous and happy. I just don't understand how such a tepid relationship could produce so much animosity in the aftermath, especially since they've both moved on.
