“Grey’s Anatomy” will be airing its Season 11 premiere on Thursday, Sept 25. And while we’re excited to see what Shonda Rhimes, creator of the hit ABC series, has in store for fans -- we have to admit, we don’t exactly remember where we left off. That’s why we’ve decided to recap all of the vital moments from the Season 10 finale -- including the show’s biggest cliffhanger to date.

The Season 10 finale episode, “Fear (of the Unknown),” kicked off on a foreshadowing note from a weatherman predicting that Seattle was about to have a “great day.” However, his forecast couldn’t have been any further from the truth when a report of an alleged terrorist attack struck the Seattle mall -- the same mall Cristina (Sandra Oh) was going to buy a charger before her departure to Sweden. For those who don’t know, the Season 10 finale was the last time Oh would appear on an episode of “Grey’s Anatomy,” which made for an even more emotional finale than we anticipated.

Once the horrific news broke, Owen (Kevin McKidd) and the rest of the Grey Sloan Memorial hospital staff sprang into action, preparing for the dozens of people about to be admitted. However, Owen was also thinking about the love of his life who, when he last saw, said she was going to the same mall that was hit.

After attempting to call Cristina (whose phone was dead) patients started rolling into the hospital. One had his eye dangling from his skull, another victim, who was also a surrogate, had her pregnancy in distress and a couple, sporting blisters all over their bodies, were looking for their missing son. But not everyone wheeled into the Grey Sloan were treated with respect. One victim was berated by officials as a potential suspect. That is, until Meredith (Ellen Pompeo) kicked them out claiming that she was the boss and that they needed to leave. Go, Mer!

Finally, our hands stopped shaking when Cristina walked through the hospital doors, proving she was alive and well. Without a second to lose, Cristina started helping patients. And she wasn’t the only non-staff member to chip in. Recently fired resident Leah (Tessa Ferrer) proved to be a vital asset to them team when she offered a helping hand.

But Cristina took a minor break from saving lives when Meredith revealed she was moving to Washington D.C. with Derek (Patrick Dempsey). “I’m happy for you,” Cristina said with an indication of sincerity. It wasn’t until the end of episode 24 did we find out why Yang was so anti-D.C. Meredith wasn’t the only one planning on leaving Grey Sloan. Alex (Justin Chambers) revealed to Cristina that he too was leaving the place where they began their residency together. “You’re putting all that talent in the drawer,” she said, her attempt at convincing him to say. She began listing off all the wonderful things he’s done while at Grey Sloan.

During Cristina’s next run in with Meredith she explained how she doesn’t want to leave Seattle. As if her procrastination wasn’t blunt enough! “I have to finish something here. None of it feels finished. You and I are not finished. I am not finished,” she cried.

Her twisted sister calmed her down claiming that this isn’t the end for Cristina. “There is no end point. You just have to go,” she said. Even after shoving Cristina into a cab to get to the airport the sassy surgeon found her way back in the hospital.

“I can’t go. We have to finish. We have to dance it out. That’s how we finished,” Cristina said. That’s when Meredith puts on Tegan and Sara’s “Where Does The Good Go” so that the best friends could have one final dance together.

“You are a gifted surgeon with an extraordinary need. He’s very dreamy but he’s not the sun. You are,” Cristina said our favorite line of “Grey’s Anatomy.” Cristina felt Derek was eclipsing Meredith by making her move to D.C. That’s when Meredith decided she was not going to end up like her father, following in her significant other’s shadow. She revealed to Derek her decision to stay in Seattle -- and he wasn't too pleased.

“There’s nothing you can do here that you can’t do there,” Derek tried to counter argue.

“I don’t want to. I live here. My life is here. I don’t want to leave,” she stated, proving she’s no longer easily persuaded by McDreamy.

But Meredith’s decision wasn’t the climax of the Season 10 finale. The most shocking moment was a scene between Maggie (Kelly McCreary) and Dr. Webber (James Pickens Jr.). Cristina’s replacement explained to him how hard it has been making friends at Grey Sloan and that the only reason she even interviewed for the job was because it was named after her mother. Looking confused, Dr. Webber asked Maggie who her mom, who Maggie said was now deceased, was.

“Ellis Grey. Did you know her?” she asked.

According to Rhimes, Season 11 of "Grey's Anatomy" will largely focus around Meredith’s storyline, which includes the struggles between her and Derek, as well as her new half-sister.
