"Look, I'm not in the show any more," Harrington told TimeOut. "I'm definitely not in the new series. I filmed some scenes of me being dead."
He wasn't giving up any other plot spoilers, even keeping mum on how long he would be sticking around.
"I know how long I'm a corpse for, but I can't tell you that!"

Fans have been ever hopeful since those final shots of Snow lying glassy-eyed and covered in blood.
Producers teased he may live, with a poster for season six featuring Snow alive, with a blood spattered face.
He has also appeared on a poster as a cameo in the hall of faces.
Others believed he may be brought back to life by robed Red Woman Melisandre, who rode to the wall, shortly after he fell.
