Grey's Anatomy Bombshell: Whose Side Are You On?

Five words added up to quite the emotional bombshell on Thursday night’s Grey’s Anatomy, raising the question: Can Callie and Arizona ever find their way back to each other?

Callie’s blunt declaration — “I’m pregnant with Mark’s baby” — came on the heels of much fan speculation and unconfirmed spoilers to precisely that effect. Could it be a final blow from which “Calzona,” already tested by Arizona’s solo jaunt to Africa, can’t recover?

Grey’s creator Shonda Rhimes offered this ray of hope to the couple’s fans when TVLine spoke presented her this week with the pregnancy talk: “I’ve always said that Callie and Arizona are MFEO — Made for Each Other — and that still holds true. They are going to go through hell before they get to any sort of [semblance] of a happy ending.”

Calzona fans, can you endure a spell of hell in the name of ultimately seeing the gals get back together? And for those of you who suspected the baby buzz was bona fide, did it play out on screen at all like you expected?

And Mark/Lexie fans, I guess we can qualify this as the “wrench in the works” that Shonda teased.
