"Grey's Anatomy" Season 11 spoilers are true: Meredith Grey will have something coming her way.  Fans would think that it's nothing that she can't handle, considering that it happened twice in her life before already.  However, this time, she is going to be totally annoyed when she meets yet another half-sister. 

Meredith already had two half-sisters before in the show. The first was Molly, who was brought by her dad Thatcher into the Seattle Grace Hospital. That was in season 2. Then the next sister was Lexie who had an internship at the same hospital. However, Lexie died in season 8.

When Season 11 returns, Meredith will experience the same ordeal, with just a different person and a different twist. This time, her half-sister's name is Maggie, who will be played by actress Kelly McCreary. Maggie will be immediately introduced in the premiere episode.

Who is Maggie? According to E! Online, Maggie is the child of her mother Ellis Grey with Richard Webber. Maggie is a love child that Ellis kept a secret. Ellis gave Maggie up for adoption, but Maggie showed up in the season 10 finale. She will be working at Grey Sloan Memorial Hospital, which means that Maggie and Meredith will see a lot of each other.

In the episode promo, Meredith isn't happy about this at all, as if her father's mess isn't enough for her to deal with. Now, she has to go through the process again. Not to mention, Meredith has to deal with her own problems, particularly with Dr. Shephard moving to Washington for a job. Meredith sure looks aggravated.

But then, Meredith did end up being close to her sister Lexie, so can this be the case with Maggie, too? What kind of revelations will Maggie tell Meredith, if there is any? What will happen to Meredith and McDreamy now?

"Grey's Anatomy" season 11 returns on ABC on Sept. 25. The long wait is nearly over. If you miss tonight's premiere, watch it online via live stream on ABC GO.
