I just realized something. Keith runs to Shiro’s rescue every single season of Voltron. Even seasons where one or the other of them barely show up.

S1 he took on Zarkon head to head for Shiro.

S2 he raced across a hostile planet and piloted Black for Shiro.

S3 he followed Black’s guidance to save Shiro from dying alone in a ship

S4 he tried to ram a shield to save Shiro

S5 he ran back and started hand defusing bombs to save Shiro

Keith really is Shiro’s Knight In Shining Armour.
