Boy (5.21)

The sad-eyed boy is an episodic character on Once Upon a Time. Arthur tries asking him some questions only to discover that he's mute in "Last Rites".

Season 5
Down in the Underworld, King Arthur can be seen opening the door to Granny's Diner before cautiously heading inside, clearly confused as to where exactly he is and what's going on. The clientele appears sketchy at best, all of them staring at him, and he eventually goes to sit at the counter next to the sad-eyed boy, who's stirring his porridge. The King asks the little boy if he can tell him where he is, but the Blind Witch soon reveals that the child stopped talking centuries ago, before offering Arthur some coffee. "No, I don't want coffee! I wanna know what this place is!" the dead ruler asserts, and Hook, who's been sitting in the back corner this entire time, comments that he thinks that's quite obvious, going on to explain to the King that he's dead.
