Everyone’s saying they wanted to see how Lance would have reacted when Keith told the group he was Galra (and so would I LOL) but if you think about it, I’m pretty sure he already knew Keith was Galra
Do you remember their first mission together?
Lance was having trouble trying to figure out the Galra’s technology
Then Keith came over and helped him out, putting his hand on the hand print, allowing them to get through
Lance was confused, wondering how he’d done it, but he’s not dumb, I honestly feel like he put two and two together eventually, probably realizing that Keith is probably Galra or has some Galra in him
And then I bet when Keith told the team, Lance was probably the first one screaming: “I knew it!” or he just wasn’t surprised at all, but knowing him he most likely bragged about knowing his secret before anyone else did
I find it so cute though that he was probably the first one out of the group to find out Keith was Galra, and that if he did know, never said anything about it but kept it to himself, so Keith wouldn’t become uncomfortable
