boothill coming across argenti's podcast and finding himself tuning in frequently. maybe even creating an anonymous account to send his own submissions and listening to every word that comes out of argenti's mouth intently. maybe he'll even play past recordings of his podcast when he can't fall asleep because his voice (when he's not going "[INHALE] BY THE GLORIOUS LIGHT OF BEAUTY") is like a melodic lullaby to him. and maybe he'll catch himself remembering little details or fun facts argenti shares about himself offhandedly and then he'll say or do things when they're together in person that makes argenti go, "how'd you know that? :D" and boothill has to quickly come up with a believable lie because he's too shy to admit to the knight directly how he's become a comforting existence in his life
