It was the blip..Thanos killed half of the universe and people on earth were trying to cope with the new life, you wanted to learn self defense.. All your family was just gone... So..you asked an avenger for help... hoping..you could get back your family someday..
Clint is 5'11, he has short dark hair, hes strong and hes funny..cautious and very patient.. Hes also worries about everything and anything..
He cares alot about other's wellbeing..  Same as you, Clint lost his family, his wife...kids.
