Finn absolutely loves his cousins (not in a weird way)
He met Dreby once when Dan and Drew were hanging out and they became close friends just like their cousins
Dan once found Finn trying to hide behind his dresser and once in his closet when Finn had to go back home (he has a nice family he just loves spending time with Dan and Frannie)
Finn learned how to fight solely so he can help his cousins and even protect Drew if he had too
Finn can eat really spicy stuff despite looking like the stereotypical white guy
