"Grey's Anatomy": Things that make you go hmm...

So, two friends end up in bed together (though we don't know whether anything happened), and the race for chief just got a little more interesting...

Plus, the fabulous Shohreh Aghdashloo as a former colleague of McDreamy's!

Next week is a re-run though. So why a new one this week in the middle of March? My theory is that they wanted to give a strong lead-in to "October Road."

Thoughts?...
