For the first time I see Meredith and Alex as a couple
Maybe it's the weakness of Riggs and Meredith. Riggs and Meredith are a bad match. I think he fits more with Maggie. Riggs has more of an off key tone that's not serious. In that way he's like Maggie. Maggie can be serious but for the most part she's light.
Meredith and Alex looked like a couple in last nights episode especially at the jail in the last scene. I think this is where they might be headed because Meredith will probably be the only one in his corner.
I never liked Jo and Alex passed a hook up that lasted too long.
