According to recent reports, "Grey's Anatomy" season 13 teases possible storylines for its brand new season. However, thanks to the unpredictable nature of "Grey's Anatomy," fans expect to see the unexpected. The release date for season 13 has already been announced by ABC. Reports indicate that "Grey's Anatomy" season 13 will premiere on September 22 at 8 p.m. on ABC network.

The upcoming season of "Grey's Anatomy" may delve into a romantic development between Meredith (Ellen Pompeo) and Dr. Nathan Riggs (Martin Henderson). The romance plot seems likely because the two admitted to having feelings for each other in season 12. However, the romance between Riggs and Meredith will not be a smooth run due to Maggie, Meredith's half-sister, who believes that Riggs has feelings for her. But Riggs and Meredith fell for each other when the latter was still reeling from the loss of her husband, Dr. Derek Shepherd.

Meanwhile, things have not exactly been smooth for Jackson (Jesse Williams) and April (Sarah Drew) in the previous seasons. However, there is a possibility that the two may reconcile in the new season of "Grey's Anatomy" as they recently became parents. But Jackson's mother, Catherine (Debbie Allen) wants to sue April for hiding her pregnancy from her son, which might affect the ex-couple's reconciliation plans.

"It's day to day with Jackson and April," Williams said. "They can have a very civil, mature conversation one moment, then be at each other's throats the next because real life is like that. We carry frustrations and baggage and grudges."
