Reaching an Understanding (джен)

When Barney Barton left Carson's Circus with the Swordsman (and most of their money), he took his deaf brother with him. Because what evil mastermind doesn't need a lackey who can't hear nefarious schemes being concocted, or tell the appropriate authorities if they ever figure it out?
When SHIELD finally catches up to his organisation, it's Clint they end up with, but understanding is a little longer in coming.
