Speaking about the finale, executive producer Debbie Allen told Entertainment Weekly that there will be multiple cliffhangers.

"There's actually two events going on at the same time that are pretty big that affect the entire hospital community. You should be worried," Allen continued. "There's cause for worry. There's an amazing cliffhanger that will have everybody thinking, 'Wow, where is this going?' "

The cliffhanger will "plant more seeds that fuel the fire for what is going to happen next season," she added.
