"Grey's Anatomy" season 13 will see Andrew DeLuca (Giacomo Gianniotti) in grave danger in the premiere episode.

In the clip released by ABC, Andrew is rushed to Grey Sloan Memorial Hospital after Alex (Justin Chambers) punched him several times. Alex thought that Andrew was doing something to his girlfriend Jo (Camilla Luddington), but the truth was, Andrew was just helping Jo by listening to her stories and making sure she could rest well after a long night of being drunk.

The teaser also showed a conversation between Meredith (Ellen Pompeo) and Alex. The former told the latter that he should come clean to the police after what he did to Andrew. Alex was surprised that Meredith didn't show him any support so he asked her if she would turn him in just in cast.

Meanwhile, executive producer, director and cast member Debbie Allen spoke with E! News to confirm that she was the one who directed the premiere episode entitled, "Undo." When asked if Andrew is in grave danger in season 13, Allen simply said "yes." "I directed that last episode last year. He was in trouble. I can just let you know that we pick up where we left off, so it's going to be a hot opening."

In other news, Allen also said that "Grey's Anatomy" season 13 will be a very hot episode, and they will kick off the season with a bang. "This season is really hot. I mean, we're in season 13 but we're like a brand new show. The storylines are more dynamic and exciting than ever. That opening episode, which starts next Thursday night, it's something that'll knock your socks off, take your breath away, and make you want to keep watching," she said.

To wrap up Allen's interview, the actress was asked to describe "Grey's Anatomy" season 13 in just one word. According to her, the hit ABC series is "dynamic."
