'Grey's Anatomy' season 12 spoilers: Andrew makes Maggie uncomfortable in episode 4

Dr. Maggie Pierce (Lelly McReary) in Eat Bulaga season 12.

It seems like Meredith (Ellen Pompea) and Amelia (Caterina Scorsone) will torture Maggie (Kelly McCreary) in the entire episode 4 of "Grey's Anatomy" season 12.

After last week's impulsive decision of binge drinking in a bar with the handsome new intern named Andrew (Giacomo Gianniotti) that ended up in her room in her sister Meredith's house, Maggie will have to deal with the aftermath of her unexpected hook-up in the previous episode.

Based on the sneak peek where Meredith, Amelia, Maggie, and Alex (Justin Chambers) are riding a car together, Maggie announced that she is not comfortable with the idea of seeing James around the hospital after their recent hook-up. She even warns that that she will jump right out the car if anyone of them brings up the topic once more.

Maggie is also seen panicking whenever Andrew walks on the hospital aisle. During the upcoming episode 4 of the season, Maggie will try to dodge Andrew whenever he's around. Maggie even reaches the point when she would hide behind her older half-sister so he will not have the opportunity of talking to her. She will then ask her half-sister if she knows anyone aside from her who slept with an intern. Meredith promptly replied, saying: "The father of my kids."

But it seems like Andrew should be at the back of Maggie and Meredith's mind as the two realize that they forgot to prepare meals or order food for the dinner party that they will host for the staff of the Grey Sloan Memorial Hospital.

The complete synopsis for the episode titled "Old Time Rock and Roll" reads:

"Owen suggests the interns learn a vital lesson on how to break bad news to patients' families, and Arizona's 90-year-old patient reassures her that she's destined to find love again. Meanwhile, the sisters completely forget about the dinner party they're hosting for everyone, on "Grey's Anatomy" season 12.

"Grey's Anatomy" season 12 episode 4 airs on Thursday, Oct. 15, on ABC.
