Among the litany of characters returning in the latter half of "Once Upon a Time" season 5 is Peter Pan played by "Heroes Reborn" star Robbie Kay and he will still be as scheming as he was when he first emerged back in season 3.

"I think his selfish intentions are still very much there. That's a characteristic that is unavoidable with fans," the young actor told Comic Book Resources about the reimagining of the fairy-tale character from Neverland.

"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 teased. Peter Pan sounds like an additional foe come "Once Upon A Time" season 5.

Kay is not at all surprised that Peter Pan is returning to ABC's fantasy hit series. The actor somehow knew that he would be back. He explained that the way the character was left in season 3 gave him the allowance to make a comeback.

Peter Pan was killed by his own son Rumple. In "Once Upon a Time" season 5, he will be one of the personalities the heroes will come across in the Underworld. Kay emphasized that his stay there did not change his ways one bit.

Another character to watch out for in "Once Upon a Time" season 5 is Queen Guinevere. Her essayer Joana Metrass teased that unwavering loyalty will be one of the character's greatest qualities.

"You can expect that she will always remain loyal. The question is to whom: is it more important to be loyal to her husband, to the king, to the kingdom or to herself?" the actress told Fashion and Style.

"Once Upon a Time" season 5 will see Emma saving Hook from the Underworld when it returns March 6 on ABC with an episode called "Souls of the Departed."
