Okay but if Keith knew Shiro had a crush on Allura, do you think he talked about it while he and allura were alone in the pod??
Imagine if Keith were trying to play wingman for Shiro, except he was really bad at it
“So… Shiro’s arm… it’s pretty cool… it could light up someone’s world.”
“Did you see how sweaty shiro was in training; it was moist.”
“He’d make a great father, even if his kids are half alien from a species he had only learned about less than a month ago.”
Or alternately: Keith being a little shit
“Once, when I was 15, Shiro got mad at me and locked me in the bathroom and the lock broke so I was stuck there for an entire day. He was so sorry he cried for three hours straight.”
