The Season 10 finale has been described as explosive – and that word may be more accurate than many initially think. According to spoilers there could be a terrorist attack in the finale, and that may lead to an explosion of some sort in the dramatic season climax.

Grey's Anatomy finales have become renowned for their tense, edge of the seat drama, and this season promises to be no different, with the show getting ready to say goodbye to Cristina Yang.

Oh announced her departure from the show a long time ago, and since then the rumor mill has been going crazy with how script writers may deal with writing her off the show.

Last week it was indicated that Yang would be leaving Grey Sloan Memorial to move to Switzerland to oversee a medical research facility. However, even though that was how things looked last week, whether that will be precisely how she leaves, or whether there will be an emotional twist in tonight's finale remains to be seen.

Spoilers have claimed that in tonight's finale, Grey's Sloan Memorial will come under siege after a terrorist attack sends dozens of injured victims into its care. April (Sarah Drew) will also reveal news of her pregnancy to Owen (Kevin McKidd).

"Yes, it's an explosive episode," Caterina Scorsone, who portrays Amelia, said to TV Line recently. "It's going to be 'all hands on deck,' absolutely. It's chaos. It's Shondaland!"

For Grey's Anatomy Season 11, fans will be delighted to know that Ellen Pompeo (Meredith Grey) and Patrick Dempsey (Derek Shepherd) have signed contracts assuring viewers that their characters will stay on for at least two more years.

Justin Chambers, Sara Remirez, Chandra Wilson and James Pickens Jr. have all also signed new contracts and so will all be appearing in Season 11. Those actors portray Alex Karev, Dr. Callie Torres, Dr. Miranda Bailey and Richard Webber, respectively.
