Oh right, is there any exposition I should know?
Fortunately I should be fairly easy to integrate. He's looking for answers (hence a rank, and probably future ranks in, things that should not be) and is very interest in anyone who shares his "crackpot beliefs" that there's something dreadful being covered up. If any supernatural shenanigans, governmental cover-ups, or pod people have occurred and becomes known to him that seems like reason enough for him to follow the current group around.
The other benefit is that anything and/or everything that comes out of my mouth may very well be true, false, misunderstood, a hazy drug fueled dream, or all of the above simultaneously. So please feel free to grab whatever hooks I may ramble out.
