As the dust from Alex Karev’s arrest settles, Grey Sloan Memorial Hospital gets back to business as usual. However, fans of “Grey’s Anatomy” know that normal is subjective.

A synopsis for episode 3 suggests that tragedy will strike amid the internal chaos at the infamous Seattle, Washington, area hospital. A car accident at a funeral will bring a family to Grey Sloan Memorial, where they’ll bicker while doctors attempt to treat their bumps, bruises and strange ailments the collision may have brought to light. The episode, titled “I Ain’t No Miracle Worker,” will be the first surrounding Arizona (Jessica Capshaw) since the Season 13 premiere. During the show she will return home from New York, to find herself at the center of the drama between Alex and DeLuca (Giacomo Gianniotti). Meanwhile Bailey’s (Chandra Wilson) busy schedule will force Ben (Lance Gross) to take on a new parenting role that may cause some contention in their relationship. Meredith (Ellen Pompeo) will also play a central role in the episode, turning to Amelia (Caterina Scorsone) for help mending the relationship between her and half-sister Maggie (Kelly McCreary) — broken by Meredith’s relationship with Riggs (Martin Henderson).

The previous episode centered around the fallout from Alex’s altercation with DeLuca. The pediatric surgeon was found guilty and charged with a felony following the incident, which leads to consequences at work. While he was not fired from Grey Sloan — thanks entirely to Bailey’s kindness — he may not see the inside of an operating room for quite some time. Instead he’ll be spending his days in the Duquette Clinic, which is grossly understaffed.

While he comes to grips with that, Meredith is trying to balance her romantic feelings for Riggs with her relationship with Maggie. During a dinner party at Owen (Kevin McKidd) and Amelia’s, Meredith thwarts Maggie’s attempt to ask Riggs out, telling him to “be nice and say no.” He obliges, which leaves Maggie staring down the neck of a half-empty bottle of tequila.

Tensions between Meredith and Maggie should be expected to stay high. During an August interview with TV Guide, McCreary opened up about the drama. While she could not give too much away at the time, she assured fans of “Grey’s Anatomy” that Maggie was going to be hurt by Meredith and Rigg’s secret relationship. The actress told the publication that fans have seen this behavior in her character before when she found out that Richard (James Pickens Jr.) was her biological father.

“One of the things that we know about Maggie, is that she is really a stickler for honesty and the truth,” McCreary told TV Guide. “In her first season, she really holds it against Richard that he didn’t tell her [he was her father] right away, that he withheld the truth for any length of time. To me, that’s an indication of how we can expect Maggie to feel about any lack of honesty, any lack of full transparency and disclosure in a relationship — especially with somebody that she trusts and, more than trusts, really relies upon as much as Meredith.”

“Grey’s Anatomy” airs Thursdays at 8 p.m. EDT on ABC.
