if you listen to Cursive/The Good Life and Bright Eyes you can catch a lot of references between them because they were friends growing up. some of them are really blunt like when Conor says in Nothing Gets Crossed Out "Tim I heard your album and it's better than good. When you get off tour I think we should hang and black out together." but there are other subtle ones like in this song it's my best guess that when Tim talks about fevers he's linking up to Fevers and Mirrors and especially the explination of the symbolism of a fever off of it.
