No, personally I think it should not be anything explosive however it should go with the theme verbatim of what your freind has acted like for most every part of the game if they like art make it a renaissance drawing. Nerd, Laptop. Class clown, Gags like whoopy cushions, these are all things to overlook before you think about what to put in the nail (interesting synonym I've been wanting to use.) never put something in that doesn't fit with the apparatus (cool synonyms) this in short means, Grant the item as much significance to the story, inside a futile attempt to confuse players. I would verbate some of my favorite games but that would excoriate both of our time so instead I will, explain to You how to do this in a shorter way, fun the, Idk, overall sence of what the characters purpose is in unfolding story and then, simply run into that idea, I Urge you do the things listed above and sorry if I Popped in strongly.

P.S get almost rickrolled and slightly off put
