Joaquim said that once you understand adam and shiros relationship, you’ll understand why keith and shiro were so close. Keith also tells allura that she has no idea what shiro has done for him (in s7). And i really really hope and think that it ties to how shiro helped keith embrace his sexuality and help him through that process (+show that the turning point in broganes relationship was keith coming out to shiro despite his issues with acceptance). If they actually end up showing that in s7? They can have my soul and every penny i own.
