Been saying this a lot. So since Lance is Keith's Stability,then that means Keith Lance's Reassurance, his go to guy when he's feeling down.
I definitely think Lance is Keith’s stability. I am not sure if Keith is Lance’s go to guy when he is feeling down though. I think for the most part Lance puts on a brave face and stuffs his feelings down. I am not sure he is really sharing them with anyone, which is why the bedroom scene was so interesting to me. The “math” must have really been bothering him, as Keith said.
What I do think Keith provides for Lance is purpose. (I am not sure if that is quite the word I am looking for but close enough) In Season 3 Keith grows to value Lance’s skill-sets and opinions. They work well as a team. Lance maybe the team “goof-ball”, but for the most part, with the exception of The Hunted, Keith takes Lance’s suggestions seriously. His thoughts are important to Keith. You can see this, even as early as S1 when they are not squabbling.
Though they squabble, they bring out the best in each other.
I think in S5, we are going to see Shiro continue to dismiss Lance’s suggestions, like he did in S4.6 and Lance is going to grow more and more frustrated. A series of events are going to lead Keith back to the Black Lion and Lance is going to realize how much more valued he feels as Keith’s right hand man as opposed to Shiro’s.
And as a fellow Leo, there is nothing we like more than to feel adored or valued.
