pro⋅spec⋅tus: [pruh-spek-tuhs] --noun: a document describing the major features

( And the title of the doc is Sam and Dean wingfic. No actual wings. I have no idea where I was going, but this bit is general audiences. )

Oh holy cow, this was going to be a crossover! With... um. Damn, I don't remember. The New York mention shook something loose, but it's not quite catching. Heroes, maybe? I don't think it was X-Men. Could be Stargate, but I don't think so. Damn, this was actually all planned out, I wish I could remember (though it's been completely and thoroughly jossed at this point, so ridiculously out of date as to be useless).

ETA: Oh! soleta remembered! It's a crossover with Constantine! Dean was going to be half-angel and Sam half-demon. I really don't remember anything beyond that.
