OK, we can all breathe a little relieved now. Well, at least for some part. After yesterday's episode of Grey's Anatomy, "Guess Who's Coming to Dinner" I at least know my heart is in condition to handle some serious emotions.
Last week's episode we learned that Callie's new girlfriend, Penny, is the doctor who treated Derek when he had the accident and died. (One moment to wipe the tears. I'm still shaken with this loss.)
Right away Mer recognizes her and Penny recognizes Mer, who starts to act weird and being nice to everyone, and we know that being nice is not something Mer is good at.
Alex obviously, as her new person, realizes something is wrong. But she doesn't say anything.
Of course, Callie is all in love and happy with the new girlfriend who seems perfect until then.
