Grey's Anatomy Flatlines A New Relationship — Plus, Is [Spoiler] Getting Fired?

This has to be a belated April Fool's Day joke, right? The April 2 episode of "Grey's Anatomy" ended with one of our favorites on the chopping block — and we don't see an easy way out of this one.

In a nutshell, Bailey spent the entire hour trying to cover up the fact that Kwan injected their patient with an experimental treatment specifically prohibited by the FDA. It was a low-key affair at first, with Bailey inventing little white lies to throw Ben off her trail, but things took a serious turn when the patient's son mentioned the hydrogel around Ben and Dr. Spencer. Busted!

Ben was understandably furious with his wife for lying to him all day, but she assured him that she had the situation under control. And what was her version of "under control," you ask? She decided to take the fall, rather than turn Kwan in and risk him losing his medical license; as someone higher up and more accomplished, she believes she's less likely to suffer consequences than Kwan.

We're not sure who this woman is, or what she did with the real Miranda Bailey, but this was a terrible plan, which she learned the hard way at the end of the hour. According to Richard, Dr. Spencer reported what the patient's son told her about the experimental treatment, and now an investigation has been opened.

The look of panic on Bailey's face in that final shot is going to haunt us for the next few weeks until "Grey's Anatomy" returns on April 30 (ABC, 10/9c).

Speaking of Dr. Spencer, she was still getting hot and heavy with Lucas at the top of the episode, fresh off last week's unexpected hookup. She was worried about making a mess in Amelia's house, but a surprisingly chill Lucas told her not to stress out. He's clearly trying to live in the moment in the wake of Katie's death, and that moment does not include dishes.

Unfortunately, Lucas' experience with a patient quickly soured his sunny new disposition. The woman, who had previously undergone a heart transplant, was struggling to find joy in life. Lucas agreed that life is "mostly a nightmare," but it's much easier if you just ignore all of the bad parts and focus on fun, which is clearly what he's doing with Dr. Spencer.

Lucas was devastated when his patient suddenly died from cardiac arrest, revealing (at least to the audience) that the wound left by Katie's death remains wide open. Instead of leaning on his friends for comfort, we saw him sobbing in the stairwell reading old texts from Katie.

As for Lucas' relationship with Dr. Spencer, we really don't see that going anywhere. When she offered to bring over dinner to make him feel better, he shot her down without a second thought, prompting Wes to offer some unsolicited (but extremely accurate) advice: "Don't waste your time. He's using you." Under different circumstances, Lucas and Dr. Spencer could probably make a pretty cute couple, but this is no way to start a relationship.

Let's check in with the rest of the Grey Sloan Memorial staff, shall we?

JO'S BABY BLUES | Jo officially returned to work this week, diving right in with an emergency C-section. Her obsession with finding the source of her patient's bleeding was beginning to worry the other doctors, but Jo was ultimately vindicated when they realized that a blood clot was blocking an important part of the patient's scan. Rather than celebrating a job well done, however, Jo spent the night wondering if her patient would forever resent her baby after almost dying in childbirth... which is apparently how Jo has been feeling about her own similar experience. When Link asked why Jo didn't say something sooner, she told him, "I just wanted to move on, I didn't want to worry you. I really love our girls."

MAMA HUNT RETURNS | Debra Mooney guest-starred as Evelyn Hunt for the first time since Season 18, though we wish our reunion with Owen's mother was under better circumstances. Evelyn was admitted to the OR after suffering a mini stroke, but she regained enough stability to tell Owen that he'll be much happier if he starts being honest about his feelings, rather than bottling things up like his father did. When Evelyn took a turn for the worse, Amelia reluctantly operated on her, with Owen promising that it would be on him if anything went wrong. Not only was the procedure a success, but there was something nice about both Amelia and Teddy being in there with their shared ex-mother-in-law. Man, this hospital really is incestuous, isn't it?

AMELIA FIGHTS FOR TONI | Toni's ex-wife remains the show's ultimate off-screen villain. This week, Celine revealed that she wants to get back together, which Toni then shared with Amelia. It put her in an awkward spot, especially because Amelia didn't feel like she deserved a say given how new their relationship is. But after crushing that risky operation on Owen's mother, an empowered Amelia put her foot down, telling Toni that "starting over" isn't going to fix the problems that were already there. "This isn't just a crush anymore," Amelia said. "Not for me." And judging by that kiss, we'd say Toni feels the same way.

SIMONE QUESTIONS WES | Wes' advice to Dr. Spencer made Simone worry that Wes might be using her, since he's only wanted physical intimacy since returning home and has yet to talk about what happened with his brother. He put those fears to rest, telling her that he's not ready to talk about it with anyone, but when the time comes, she'll be the first person he trauma dumps on.

Well, we have a lot think about over the next four weeks: How is Bailey is going to get out of this mess? Do you think there could be something real between Wes and Dr. Spencer? And with only a few episodes left, how do you predict Teddy and Owen will be written out at the end of the season? Drop a comment with your thoughts below.
