my friend: Why do you think Lance asked Keith, “Is the princess ‘with you’ with you?”
me internally: In animation, every action, every line of dialogue, every scene is planned out and has a purpose. You can’t just add a scene without it meaning something later on, or else it would be a waste. It has already been established that Allura is not interested in Lance, and in season 2 Lance really doesn’t pay her that much romantic attention. In fact, most of the romantic tropes used in animation and entertainment, in general, are used with Lance and Keith. And throughout the seasons they have hinted at Lance and Keith’s bond with their ‘rivalry’ and then making a good team and then being the two colors that make purple, which is a prominent color in the show. Lance’s “’with you’ with you?” line wouldn’t really make sense if he was asking if Allura was dating Keith because at this point he wouldn’t care about Allura being with someone, but it would make sense if Lance was subtly asking if Keith was single because he has a crush on Keith. Lance’s interest in Keith has been stated to have begun at the Garrison, and he is constantly inserting himself between Keith and others and always trying to get Keith’s attention somehow. This and the fact that a storyline about Lance’s insecurity may hint as him feeling as if he is insecure not only in his abilities as part of the team, but confusion about his sexuality and insecurity about crushing on someone who he sees as one of the most talented people he’s ever known. Therefore, asking if Keith is dating Allura is a sign of his interest in Keith and a subtle hint at their future storyline(s)/interactions and Lance’s own storyline.
me externally: lol who knows
