Poor Maggie!

A secret's never a secret for long in the world of Grey's Anatomy, and judging from this new sneak peak Meredith (played by Ellen Pompeo is about to learn that lesson.

Meredith and Nathan might have saved the lives of the passengers aboard the aircraft, but did they cause their personal lives to go up in flames?

The sneak peak shows a visibly upset Maggie (played by Kelly McCreary) confront Meredith about her budding romance with Nathan. She peppers her with questions including, "Did you join the Mile High Club?" Alex Karev (played by Justin Chambers) is sitting alongside the half-sisters, and even tries to leave because of the palpable tension!

Meredith then tells her that they can discuss the situation elsewhere, but Maggie instead decides to leave. It's clear that Maggie feels betrayed that Mer hid her relationship with Nathan despite knowing that Maggie had feelings for him. We wonder if the women will be able to move past this!
