In which Lance is easily distracted, and Keith is quick to exploit that. So the thing Lance has learned about Keith is that he has a long, long memory. It's selective as hell, but if Keith cares enough about something to notice it in the first place, he'll never forget it. And because it's Keith, he'll usually remember whatever it is at the worst possible time.

Keith thinks he's about to get rickrolled. Keith is mistaken. When he opens the email, all it says is Saw this and thought of you, happy birthday buddy, followed by a link to a video hosted on a Google drive. Keith gives it a long look, weighing suspicion against curiosity, the fact that he knows the sender of the email against the fact that he knows the sender, and then shrugs suspicion aside. He's probably about to get rickrolled, but whatever. He clicks the link. It's not a rickroll.

They say no plan survives contact with the enemy; Shiro probably needs to keep that one in mind. Lance pushes everything, like he can't help himself. In retrospect, Shiro has no idea why he expected anything else from him in bed.

Matt has a plan to get Shiro laid; Shiro has a lot of misgivings about this. "Shiro. Buddy. I swear on everything I hold holy—" "You're an atheist," Shiro points out. "—I swear on the grave of Carl Sagan and in the name of Neil deGrasse Tyson," Matt says, not missing a beat, "that if you go home alone tonight, it'll be your own personal decision and not because you won't have other options."

Keith and Shiro play chicken. Sex chicken. Everybody wins. "What do you think you're doing?" "What does it look like I'm doing?" Shiro has an excellent poker face; it doesn't even flicker when he says, "Demonstrating the male version of the human reproductive system. Why are you doing it on my lap?"
