*spoilers possibly* Casey references?
 

I haven't seen the movie yet, but I've read all over that we've had confirmation from Will Arnett that Casey and Vern are cousins. I haven't seen the interview where he states it. However, does Vernon mention Casey at all in this movie for anyone that's seen it? Thank you.

Not that I noticed. And I haven't heard this "cousins" thing before, either.

Tons of sites are stating that Will Arnett said that Casey and Vern are cousins in the movie universe, I can't actually find any confirmation he said that but just wanted to see if he mentions it in the film.

ive actually also read that somewhere... but no there is no mention of casey at all
