The previous season of "Grey's Anatomy" did not feature any significant deaths. The last major death on "Grey's Anatomy" was that of Patrick Dempsey's Derek Shepherd, who died in a road accident. Since then, rumours have been rife that another major character will die, with Richard being a possible target.

Richard is one of the few remaining people from Season 1 of the hit medical drama, and the previous season showed him looking unhappily at the crumbling relationships around him. According to some viewers, Richard has been exhibiting signs of fatigue, and it won't surprise them if he suddenly drops dead in the next season.

While not much is known about the plot of Season 13, it's rumoured that the next season would feature a lot of reconciliation. April and Jackson, who welcomed a baby in the Season 12 finale, could end up getting back together as they care for the baby.

"I think the big question we're left with is, like, 'What's gonna happen with April and Jackson?' I don't know and I'm sorry to say that. I wish I do. Although it's really fun to be surprised, it really is. They've been through so much together, and I feel like this baby could really bring them back together," Sarah Drew, who plays April Kepner, told ETalk.

However, one relationship that is going to go through tough times is that of Alex and Jo, who revealed in the Season 12 finale that she was already married and that was the reason why she has been refusing Alex's proposals. Chances are high that the next season will introduce viewers to Jo's abusive husband, from whom she has been hiding all this while.

"Grey's Anatomy" will return to ABC in September. Filming for the upcoming season will begin in August and it will pick up immediately following the events of Season 12 finale.
