Post-AOU. Clint becomes Wanda's mentor, responsible for her training and her discipline. When she recklessly puts herself in danger one too many times, he decides that the verbal lectures clearly aren't cutting it, and takes her over his knee for a good-old-fashioned spanking.

He's careful to be pretty gentle about it, and when he's done he asks her if she's finally learned her lesson. But when her response to the question is a mumbled "yes, Papa," Clint is left treading a fine line as he tries to figure out if Wanda's slip of the tongue is because she sees him as a father figure, or because she's into daddy kink.

Author gets to choose the outcome.
