Don't expect a big character change for Peter Pan (Robbie Kay) in the 100th episode of ABC's Once Upon a Time.

How The Underworld Is Just 'The Tip Of The Iceberg' On 'Once Upon a Time'

Kay's Peter Pan is one of many characters from Once Upon a Time's past who is returning for the 100th episode. With our heroes trudging through the Underworld, they will witness such villains as Pan, Cora (Barbara Hershey) and Sidney Glass (Giancarlo Esposito).

Even though Pan was damned to the Underworld and has had time to reflect, Kay recently spoke with Comic Book Resources and said his character hasn't exactly changed.

"Being in that scenario has given him time to think and reflect on what's happened and time to maybe step back and say, 'Maybe I was wrong. Maybe there are different ways to go about things.' I think his selfish intentions are still very much there," Kay admitted. "That's a characteristic that is unavoidable with fans. He's always going to try and find an angle, try and manipulate people into doing things that will eventually benefit him. When we return for the 100th, you'll be seeing a fair bit of that."

Kay wasn't totally surprised to be invited back to Once Upon a Time, saying he thought there was always an option for a return, despite his unfortunate fate in season 3.

It is currently unknown how prominent of a role Pan will have in the 100th episode.

Once Upon a Time returns for the second half of season 5 on Sunday, March 6 at 8 p.m. ET/PT on ABC.
