A great friend who will have loyalty towards any body he feels deserves it and had earned it. Pawnee often treats people who have the potential to be a good person, accordingly and by what he sees in them, rather then treating them according to what they show him. In any case though, Pawnee doesn't put up with childish games nor will he ever entertain anyone who shows even the slightest hint of being a gaslighting game show host such as a Davona.
Brett: Hey guys, you want to go to Pawnees house to go swimming?
Friend: I would but no don't have swimming trunks or a towel.
Brett: No worries!! My buddy Pawnee has extra trunks at his house that he will let you use and even keep them if you need them.
