While most of Grey’s Anatomy Season 9 has been focused on taking back the hospital, now that Grey Sloan Memorial Hospital is up and running, it’s all about the patients.

On the heels of the ER reopening, there’s trauma galore, and in Season 9, Episode 19: “Can’t Fight This Feeling,” Owen and Meredith are at the center of it for two entirely different reasons. If you can’t wait until tomorrow, March 28, to find out about the explosive cases and relationships, have no fear — we’ve rounded up all of the juiciest spoilers about the episode right here so you can brace yourself for the tragedies ahead.

Sarah Chalke is practicing medicine again — but she’s no Dr. Elliot. While the Scrubs guest star does have some medical knowledge in this episode, it’s only because of WebMD. As seen in the promo, sneak peeks, and photos, she plays a distraught mother whose son is very sick, yet can’t be diagnosed. And the person who helps her is...

Meredith is particularly maternal (and hormonal) as she takes a case close to heart. Considering how much Sarah screams in the promo for someone to “find her another doctor,” we’re guessing that Mer steps up to the plate. In a sneak peek, she carefully goes through every possibly disease or illness with the worried mother, acting more like a mom than a doc, which could lead to interesting consequences. On that note, someone else is having some patient bonding time...

Owen takes a special interest in a young patient when tragedy strikes. After a terrifying gasoline explosion on the highway (which causes at least one patient to erupt in flames), the ER is flooded with patients. In addition to urging people to “be safe,” Owen takes a 10-year-old boy under his wing, ensuring he knows “everybody is safe” and distracting him from the fact that his parents are in critical conditions. This seems like the only bond that’s happening in this episode, though, considering...

Things heat up in a bad way with Alex and Jo and Jackson and April! We refuse to give up on two of our favorite new ‘ships, and in this episode, the former couple and will-they-won’t-they couple both run into each other — and it ain’t pretty. April’s encounter is more awkward — she finds Jackson massaging her boyfriend’s ass, treating him after Matthew was hurt in the explosion — but Alex’s “douche”-off with Jo’s boyfriend, Jason, is all kinds of uncomfortable, too. Will these crazy kids just get together already? We know that there will be more Japril and that she’ll cry on his shoulder, but as for Alex and Jo? Hey, anything can happen!
