On Grey's Anatomy Season 11 Episode 4, secrets from Ellis Grey's past come back up when Meredith watches old videos and reads through her mother's journals.
Also, we learn more about Ellis and Richard's relationship.
Through Richard, Meredith finds out the reason why her mother tried to take her life. The day at the carousel that has played in her mind over and over was when Richard told Ellis that he was leaving her. Meredith realized that she did remember calling 911 when her mother tried to attempt suicide and also the nights at the hospital. She also recalled seeing her mother pregnant and hearing Maggie cry when she was five years old.
Elsewhere, Maggie makes an unexpected announcement that takes the hospital by surprise as she announces her resignation.
Meanwhile, Alex finds out that Bailey was unanimously voted to the board. He gets new responsibilities as Arizona decides that she needs to focus on her marriage with Callie and the fellowship.
Ultimately, Meredith comes around and takes baby steps to show her sister that their mother did know and cared for Maggie. Is it enough to convince Maggie to stay? That's still undetermined and we'll hopefully find out next week.
