Shonda Rhimes warned us that all bets were off for the Grey’s Anatomy season finale, appropriately titled “Perfect Storm,” that put several Grey Sloan Memorial doctors at risk. Warning, major finale spoilers ahead!

Upon learning that Ethan’s father survived his surgery, Owen decides to transport Ethan and his father to another hospital – in a helicopter during the storm. Although he advises Ethan he’s just getting moved to a “safer” hospital, Cristina is well aware that this has to do with Owen’s desire to adopt the boy. Cristina criticizes Owen for not talking to her about this. He insists he doesn’t want kids – he wants her. Their conversation ends when Cristina learns that Meredith is in labor and rushes off to see her.

Elsewhere, Shane and Ben are preparing to work with Bailey in the OR. After a few minutes in the OR, Bailey freezes and insists she can’t operate. She leaves and asks Owen to find a surgeon who can take her place. Richard volunteers and speaks with the patient’s father who fills him in on his son’s condition. Owen is visibly upset that Bailey opted out of the surgery, but after Cristina’s PTSD debacle you’d think he’d have more compassion. Callie on the other hand does and asks Bailey to stock the ORs with blood.

Richard joins Ben and Shane in the OR as the power goes out. He reminds the doctors to stay calm and advises Shane to get Cristina, who’s preoccupied with Meredith. When he goes to see Cristina, Meredith insists it’s fine for her to go. She has more important things to deal with – like advising her doctor that she’s going to push. Meredith’s doctor puts her in her place and insists that there’s no way she’s pushing. Due to the baby’s location, Meredith is forced to have a C-section. She’s all set to go into surgery when the power goes out. Derek advises her to stay calm. He insists the power will come back on shortly, but it never does. As a result, Meredith is forced to undergo her surgery in the dark.

After her dirty deed with Lauren, Arizona rushes out to the NICU to advise the doctors to stay calm. If they appear spooked, the parents will get spooked. Lauren comes in to offer some assistance. After some initial hesitation, Arizona lets Lauren help out with her patients. Alex attempts to resume his talk with Jo but Arizona interrupts him, stating that their patient’s monitor is low on battery.

When Bailey comes in to bring blood to the OR, Richard mistakes her for a nurse. He later apologizes before she walks out. Ben confesses that he tried to talk to Bailey, but his attempts came up short. Cristina enters to assist Richard but refuses to operate in the dark. Richard talks about how his patient was helping his father prepare for the storm when it hit. Without her help, he’ll die. Richard’s advice is enough to convince Cristina to operate.

Meredith undergoes surgery for her C-section in the dark. Her doctor gets the baby out without a problem, but he doesn’t initially cry, causing Meredith to panic. Eventually, he cries, but Meredith and Derek learn his stats are low. She advises Derek to go with the baby while she gets stitched up. Meredith’s doctor gets paged to another patient, leaving Shane to close Meredith up.

April is taken off guard when she sees Matthew enter the ER during the storm. He explains that he walked over to the hospital after his ambulance got stuck in water. When he offers to help out, the doctors witness a bus flip over on the road, causing it to catch on fire. The doctors rush to help the passengers escape before the whole thing blows up. Jackson and Owen assist a patient who’s stuck inside. She advises them to find her daughter.  Jackson makes his way up to save her, but it doesn’t seem like they’re going to make it out in time. The bus ends up exploding, causing the doctors to scream in horror. April is convinced Jackson gets killed in the blast, but he makes it out alive – with the child – in a scene fit for a movie. Callie examines Jackson after his heroic act until April runs in and pushes him out of anger. Callie tells her to get out and cool off. Her true feelings emerge as Matthew looks on.

Alex finds Arizona in a closet, searching for batteries. He advises her that another battery light went out in another machine. As the two search for spare batteries, Arizona blabs that she cheated on Callie with Lauren. Alex confesses he’s in love with Jo but can’t tell her, sharing that all the women in his life were “fine until they met me.” According to Alex, he’s the worst person in the closet.
