here comes a thought,,, Dream,Seam Lance getting so comfortable around Hunk that he sometimes puts his head in his lap to relax. It makes him feel like they're really close even though he's not paying attention to whatever Hunk is tinkering with. Hunk adores this so much. Without thinking, one day he runs his fingers through Lance's hair, and Lance's reaction is so absolutely adorable that Hunk can't stop doing it. Lance is just one big smile, pushing his head into the touch like a happy kitten.
Ahhhh, my heart! Yes, all of this, absolutely. After his conversation with Shiro, in which Lance learns that it’s okay to actually seek out touch, not just wait in hopes that it will come to him, he’ll slowly get more and more comfortable with initiating contact with the others. Especially with Hunk, who is always so open and accepting and kind. I can see this scene happening a lot, actually. Eventually, he’ll do like he did with Thace back at the beginning, except a lot more confidently–just pick up Hunk’s big ol’ huge hand and put it on top of his head like a hat, and Hunk will immediately understand and start ruffling his hair, to which Lance will give a big, contented smile.
