I completely agree. They've all seemed to reach a real point of maturity in their lives, and I think it's highly reflected in their relationships. Alex and Izzie are married. Meredith and Derek are "married" but still the strongest couple right now. Callie/Arizona and Owen/Cristina are presumably in it for the long haul, TV show drama along the way notwithstanding but I really do believe they'll all be fine by the end of the season. I could see problems with Lexie and Mark maybe because of their age differences, but right now they're very stable. Basically, any of these couples could have children in the fairly near future, so for her to dismiss that potential storyline is stupid IMO. Time goes slow on Grey's, they can introduce babies, and then simply avoid the Desperate Housewives-like 5 year jump, and we'd never even have to see the kids, but at least they'd have them. I would much rather see that than the constant break-up/drama storylines this show loves to rely on.

Think about it, a bitchy and pregnant Cristina or Callie would be comedy gold. Or maybe they'd go with Arizona, since she's in pediatrics.
