So everyone basically agrees that Shiro is the space-dad, but what if Lance turns into the space-dad once he and Keith start dating?

Like his protective-family-side shows up and he’s the one who makes sure everyone is well taken care of - especially Shiro (who would become Lance and Keith’s son):

Lance: Shiro, I don’t care if you’re the black paladin or not but you are NOT going out there looking like a hobo.

Shiro: But I’m YOUR leader, you can’t -

Lance: SHIRO don’t make me call Keith.
