Do you think Keith and Lance have a thing for each other?
If I'm not answering truthfully then I would say no but since I am I would say it's something like this.
I think that Keith likes Lance because of his outgoing personality and I feel like he envies Lance because of how happy and positive he is able to stay. To me Keith is attracted to Lance and does like him in I guess a romantic, weird, terrifying sort of way.
As for Lance I honestly have no clue. Either Lance is really Oblivious and dumb or he's just trying to make Keith jealous. Either way yes I think they did have a "thing" as you call it.
New hint unlocked:
Shiro thinks that Keith and Lance have a complicated relationship that is affecting the team.
