(1) After getting soundly chewed out by all of team Voltron for his insane stunt at Naxzela, Keith joins Kolivan at the negotiation table, with his mask up, while the talks between Lotor and the Coalition begin. And he can see how frustrated everyone soon gets because Lotor is just TOO good of a liar. He could tell them all that he's actually part Kaltenecker instead of part Altean and they'd be hard-pressed not to believe him. So Keith decides they need to find a way to knock him off-balance

(2) enough to maybe shock a straight answer or real emotion out of him. And, having learned from watching Lance, he decides the best way to do this is to flirt with Lotor outrageously. Only, because he’s Keith, he doesn’t do it with smarmy smirks and corny pick-up lines: he straight-up takes his mask down, goes up to Lotor with a look of complete honesty, and says in all seriousness, “You’re the most beautiful person I’ve ever laid eyes on.” And just goes from there.

(3) And Lotor actually BLUSHES. Like, he’s used to being flirted with but not by someone so pretty and intense and guileless, and it’s hard to focus on being a genius possibly-villainous mastermind when his hands are being cradled so tenderly by much smaller ones and huge, shining purple eyes are staring so earnestly into his own. (Meanwhile, team Voltron and the Blades are choking on their tongues, and Shiro knows what Keith’s really up to but is still very much Not Happy about it.)
