It’s that time again, Grey’s Anatomy fans: finale season. Next week, we head into the first episode of the two-part Season 9 finale (Episode 23: "Readiness Is All," May 9) and with a superstorm brewing, there’s a lot of drama ahead.

However, the question is, how much drama should we expect? We're constantly looking for clues about what's coming up next, and what better source of info than the promo itself?

We've taken a close look at the American and Canadian previews for Season 9, Episode 23: "Readiness Is All," and honestly, we’re nervous for what’s ahead. Here’s what we gathered from our frame-by-frame analysis of the latest promos.

MerDer’s baby is in danger. As we predicted, Meredith and Derek’s second journey to parenthood won’t be any easier than their first; in fact, it may be even more scary and difficult. In both promos, we see Meredith trip and fall down the stairs, putting both her and her baby’s lives in danger.

Is Jackson’s life in jeopardy, too? In the American promo, we see a tree crash into the window of the hospital, appearing to almost hit April and Jackson. Then, in the Canadian promo, someone who looks very similar to him is being examined by Derek, and Alex bursts in to say, “You gotta help him.” Is Jackson in danger?

Bailey is getting worse. Even after finding out that her patients deaths’ were faulty gloves’ fault and not her own, Bailey is still having trouble coping with her MRSA problems. Though husband Ben is back and trying to help, she still thinks “she’ll kill anyone she touches.”

The superstorm even has Owen worried. Trauma extraordinaire Chief Owen Hunt is usually calm, cool, and collected, but as he explains the storm ahead, even he looks worried. “Massive storm's coming: hurricane, force winds, and heavy rain,” he warns.

An intern is going rogue! It looks like intern Heather Brooks is flying off the handle and trying to tackle a solo surgery. We see Cristina yell, “No, mousie, no!” but it’s difficult to tell exactly how badly Heather is behaving. We’re sure there will be consequences.

Alex and Jo get closer — and he confronts Jason. In the sad aftermath of yesterday’s episode, we know that Jo is a victim of domestic abuse. She came to Alex for help, and with the help of an ice pack and a safe place to stay, she is slowly but surely healing. However, he also appears to confront her boyfriend, Jason, so who knows what will happen with this triangle.
