"I dig the fans. If it weren't for the fans, we wouldn't be celebrating 15 right here," Pickens Jr said of the show, showing gratitude to the series' fanbase. "Different actors have different takes on fans and what fans quote unquote require of them."

"I think it's a privilege that we've impacted their lives to such an extent that they have been willing to take this journey, right now going into our 15th season," he added.

Doctors Avery and Pierce have been toying with a romance for some time and it sounds like season 15 will see them fully realize that relationship.

"Maggie and Jackson are exploring love they have finally claimed," Grey's Anatomy executive producer Krista Vernoff teased.

Chambers recently recalled feeling a lot of "nerves" while shooting the Grey's Anatomy pilot.

"I was with all these other actors, I didn't know anybody, and I was hoping the show would be a success and thank God it worked out," he added.
