Some of my inktobers
I feel like with Allura, Lance's reactions show how much he has grown. It makes sense that he's the one to help her out while Allura is struggling being a paladin. In S3, while she was comparing Alfor and Lance, i got the feeling that she was also entrusting Lance to support Keith. ("I won't let him down.") None of those actions are proof of romance ofc but after they grew so much respect and trust between each other, i doubt there will be a love triangle. It would make no sense.
