I think that the action of Keith giving his father's vest to Shiro is such an intimate show of how close he considers Shiro to be to him and how much he trusts Shiro with such a fragile memory of his past 🥹🥹
*ALSO THE FACT THAT SHIRO WEARS THIS SAME VEST FOR LIKE 90% OF THE SHOW LIKE HE DEF HAS OTHER CLOTHING OPTIONS AT THAT POINT BUT HE DELIBERATELY CHOOSES TO WEAR THE VEST THAT KEITH GAVE HIM OVER AND OVER AGAIN AUGGHHH IM SICK
