Meredith And Miranda's Row Over A Liver

Both realizing the importance of the lives of their patients, it seems like Meredith Grey (Ellen Pompeo) and Miranda Baley (Chandra Wilson) are having a disagreement over one liver. Will they be able to resolve it soon?

Amelia Reveals Good News To Owen

After realizing he needs some help in babysitting, Owen Hunt (Kevin McKidd) seems to be enjoying attending to kids. His wife Amelia (Caterina Scorsone) has some good news to share with Owen. In all certain ways, Owen will be delighted to know that Amelia is pregnant.

Marika Dominczyk Cast As Eliza Minnick

"Criminal Minds" star Marika Dominczyk has been confirmed to join "Grey's Anatomy's" roster of cast. Dominczyk plays Eliza Minnick. As the name revealed does not ring a bell yet, different speculations have surfaced.

According to recent reports, Eliza is Owen's sister. This though is likely to be false considering her last name. Even so, creatives of the show always have the extra pellets for their gun as she might be revealed as Owen's sister after all, of different parents perhaps?

Other reports pointed out that she might be Arizona Robbins' (Jessica CApshaw) new love interest. Yet others said she might just be an ordinary patient. There is no confirmation as well as to until when she will be starring on the show.

In another news, there have been rumors sticking around that Izzie Stevens, played by Katherine Heigl, might be back on the show full time. The original "Grey's Anatomy" character had not been ditched from the show by death which means comeback is possible.

"Grey's Anatomy' season 13 airs Thursdays at 8 p.m. ET on ABC.
