I feel like in Voltron the creators do a really good job of showing how much Keith and Lance care about each other separately
Keith is really caring and gentle towards Lance when he’s hurt
But he’s also not afraid to express how he’s coping when Lance is away from him for a long time, he’s impatient and stressed, he just wants him back to normal as soon as possible. He wants to see him healed and OK again.
And then there’s Lance who’s a lot more forceful and serious, he knows Keith is in danger so he wants to go down and protect him. There’s no hesitation, he doesn’t care what he’s getting himself into as long as it means Keith comes out safe and alive
But he’s also fearful, because he’s scared that he might lose him and he’s not sure how he’ll be able to cope if that does happen
It’s such a good way of showing that even though they’re always at each other’s throats, in the end they really do truly care about each other.
These situations show that they pretty much can’t live without the other, and that they also have a very special and important relationship. Gradually as the show goes on, I think they’ll both come to realize that.
