Character development is Aragorn finally washing his hair at the end of Return of the King
Although! He did wash it in Rivendell, in the first movie.
…although I doubt he wanted to…
Elrond: “Come over here, Estel. I have something to show you”
Aragorn: *walks over*
Elrond: *grabs Aragorn by the neck and shoves him face first into a bird bath*
listen, aragorn son of arathorn is the only man who can go six weeks between showers and make you think ‘rugged good looks, probably smells of tobacco and well-worn leather, but like, in a good way’ instead of ‘pop 12 cranberry pills and hope for the best’
