Amelia and Owen are definitely excited to build their own family just two months after they got married. In "Grey's Anatomy" Season 13 episode 7, the pregnancy scare is now bringing her dark past, where Amelia, who was a past addict, lost her baby back in "Private Practice."

"The pregnancy test triggered the bridge between those compartmentalized pieces of her life," Scorsone told TVLine."And all the trauma that she experienced came flooding into Seattle in a way that she [hadn't anticipated]. She's suddenly being hit with the reality that she can't really run away from the past."

In an interview with Entertainment Weekly, Scorsone was asked if the emotional turmoil that Amelia is facing in the new episode of "Grey's Anatomy" Season 13 could trigger her to relapse. The actress teased that a relapse could happen to anyone who is not strong enough to face the triggers such as life's stresses.

There is a good possibility that Amelia may try to get out of her troubled past by returning to her addiction as Scorsone revealed that relapse is something that will always be with the neurosurgeon. The "Private Practice" star added that she thinks that Amelia is not strong enough to resist it.

As Amelia faces to struggle about her past when "Grey's Anatomy" Season 13 returns, the entire doctors in the Shonda Rhimes medical drama are placed in great danger of getting fired. Dr. Catherine Avery (Debbie Allen) and Dr. Miranda Bailey (Chandra Wilson) are reorganizing the entire structure of the hospital's program, and it is either someone may get transferred or dismissed.

The move will place the entire doctors out of their comfort zone. As the shake-up threatens everyone, Dr. Richard Webber (James Pickens Jr.), requested Dr. Bailey to find a good way to make the announcement.

"Grey's Anatomy" Season 13 episode 7 will return on Nov. 3, Thursday, at 8 p.m. on ABC. Watch the official trailer of the new episode:
