Here's a sketch of my OCs Oren and Alder. They're from a fantasy world in which their lacquered hair is a sign of social status.
Alder's a knight--as signified by his mighty hair helmet--and Oren's his squire, but that's just the beginning of their relationship. Alder's attitude toward is less that of a knight to his squire and more like that of a doting parent to a child. Oren, who's sure he's ready for dangerous adventures and harsh training on the path to knighthood is continually thwarted by the embarrassing over-protectiveness of the knight he's sworn to obey.
Potential dialog:
"Oren, are those boys picking on you?"
"No, Sir Alder, we're just talking. They're my friends."
"If they're picking on you, they're not your friends."
"They're not picking on me."
"Are they trying to pressure you into drinking?"
"I mean...we were thinking about going to a pub."
"Not alone you're not. Someone's got to watch your back."
Cut to an hour later. Alder's laughing drunkenly with the pub's patrons, and Oren's still completely sober. The closest Alder lets him get to alcohol is his own mug of ale sitting on Oren's flattop. A passing waitress thoughtfully puts a napkin under it so it won't leave a ring.
"Thank the nice lady, Oren!"
(Sigh) "Thanks."
