‘Grey's Anatomy' Season 13 spoilers: Tessa Ferrer's Leah arrives shakes up Grey Sloan Memorial Hospital

"Grey's Anatomy" Season 13, episode 7 will introduce a new character named Leah (Tessa Ferrer).

In "Why Try To Change Me Now," Leah, who works as an education consultant, will arrive at Grey Sloan Memorial Hospital to assess the programs they are offering. The staff at the hospital will be terrorized by her arrival because they have heard so many things about her. In fact, everyone is also aware that Leah didn't have a good relationship with her colleagues in her previous hospital.

Meanwhile, Alex (Justin Chambers) will blame himself for Leah's visit at the hospital. After all, he was recently involved in an altercation with a fellow doctor. Dr. Miranda Bailey (Chandra Wilson) was therefore forced to downgrade his services from being a surgeon to a clinic nurse.

In the sneak peek released by ABC for episode 7, Dr. Webber (James Pickens Jr.) will confront Dr. Bailey about Leah's arrival at the hospital. Their conversation will prove how both doctors have very opposing opinions on certain things. In the end, Dr. Webber will question why Dr. Bailey is so eager to work with Leah. He asks her if she has any plans to have him replaced by the newbie.

In other news, "Why Try to Chance Me Now" will also see Amelia (Caterina Scorsone) and Owen (Kevin McKidd) fighting over their personal issues. However, since the couple is working at the same institution, they wouldn't be able to set their problems aside at the workplace. This will result in conflict with the other doctors as well.

Elsewhere, April's (Sarah Drew) relationship with Jackson (Jesse Williams) is improving week in and week out. However, April also wants to explore some unchartered territories. Her decision to do so may impact his relationship with the father of her child.

"Grey's Anatomy" Season 13, episode 7 will air on ABC on Nov. 3 at 8 p.m. ET.
