Grey’s Anatomy rolls out the welcome mat for a Maggie-centric episode with season 11, episode 2, “Puzzle With a Missing Piece.” Read our full recap here!

Cases of the Week:

•An elderly woman wishes to pass away.
•A teen with heart problems is trying to pass a kidney stone.
•A woman risks her own death in order to give birth to a child who will be born with a heart problem.

Solve for X: Maggie likes puzzles. The New York Times crossword, solving a patient’s heart failure in time to save their life, all in a day’s work for the newest cardiac resident. One puzzle she cannot seem to solve, however, is Meredith Grey. Richard tries to assuage her into continuing on the path to peace, but, truth be told, it’s not for the sanity of the hospital staff getting along. No, Richard wants his surrogate daughter and his newly discovered daughter to play nice.

Hang in There Robbie: Maggie takes Jo aside to reprimand her on the proper protocol for patient-family interaction. By yelling at her, Maggie releases her thunder. When working as a pretty, small, female, sometimes one must “bring the thunder” to make their presence known. Maggie is trying really hard to get her own notorious line on the show in the way of McDreamy and “Seriously.” Enter Miranda “The Thunder” Bailey.

With no time for research as she adjusts to the life of cardiac resident, Maggie asks for Robbie, the kidney stone patient, to get a genetic work up to test family history. The board may have voted to close Bailey’s lab, but she still has a set of keys (and a pretty strong grudge against the seat-holders). Karev calls Maggie in for a consult, but much to the dismay of his new private practice partner, Maggie mentions that Alex is up for a seat on the Grey-Sloan Memorial board, which means he may be leaving the practice. Well, Maggie, that mistake is all on you, dear, and kicking Jo off of your service is not going to erase that.

The “Cool Kids” Table: As if running into your half-sister, her happy child Zola, and gorgeous renowned neurosurgeon husband wasn’t enough to ruin your appetite, how about not being welcomed at their table? Even with Derek’s extended olive branch, the smugness of Meredith Grey keeps Maggie at a 100 foot distance.

When you realize that your sister adopted a surgically needy African baby, she is cast in a whole new light.

Let Go of My Hand: The story of Rita, the pregnant woman with a tear in her aorta, follows the residents of the hospital. As Rita begins to lose her battle with her own heart, her husband informs Maggie that they previously lost their other child all because Rita let go of her hand and a freak accident led to her falling and hitting her head. Now that he faces losing them both, he blames Rita for not making the decision to let go.

Ellis Grey lets go. Maggie let go of her stable happy family life in Boston. Arizona and Callie are working through letting go of their career aspirations or their second shot at motherhood. Richard would not have let go of Maggie had he known.

Two for Maggie: By calling McDreamy “The Other Dr. Shepherd,” Maggie wins points with Amelia Shepherd. When she calls out Owen and Avery for their lack of foresight in closing down the genome research facility, she gains a friend in Bailey, who likes her spunk.

Amelia begins to chat up Maggie for a little girl talk, the seeds of friendship brewing. From her stint on Private Practice, Amelia may be the glue that keeps Maggie from falling apart before her puzzle is complete. As Amelia comes to her side, her parents send a bigger wedge between her new cronies and herself, a singing fish sized wedge. They want what is best for their little girl, and making friends is on the top of that list.

Can you blame Maggie for the mud she seems to drag herself through? When you break down everything that Maggie did on this one day, she deserved probably half of what she got in return. Sure, a few Sherlock moments are impressive and she is a brilliant surgeon, but she needs some work in the social skills department.

A Little Rule Breaking: With a little perseverance and a few favors from Bailey and Jo, the mystery of the family with cardiac failure is solved. There is a genetic mutation that causes cardiomyopathy. Owen is impressed with her discovery in the wake of Cristina’s departure. Another win in the Maggie column. (And a huge win in the Bailey column, too! Perhaps closing that lab was a poor choice.) One more person to join team Maggie is Jo. Refusing to take “no” for an answer, Jo brings the thunder and works her way back on the cardiac service.

Putting a mother and father at ease that they are not causing their children’s illness, Maggie moves on to take care of her elderly cancer patient. Pushing Meredith aside, Maggie barely puts any effort into reviving the woman, choosing instead to honor the patient’s wish to pass on. This puts a damper on the sisterly bonding. That is until Grey steps in to deliver the news with certainty to the patient’s family that Maggie did everything in her power to save the mother.

The final piece of the puzzle, telling Meredith Grey that they share a mother. However, the piece does not quite fit. Meredith accuses her of lying and continues on into season 11 with her “out for blood attitude.”
