One of your characters finds the other's journal/notebook/sketchbook. Show what they discover inside.

The first one I got was "one is messy and one is clean"

And that would not work

craftyviking: well, a lot of people portray Rude as a very clean and orderly person and Reno as a messy gremlin, so it could work, lol

but I also like the other one .. like, who has the tons of detailed shirtless sketches and drawings of the other in his book? xD
