Eddie had a fresh cell, real young and barely-blooded sorts. He was worried about being able to handle an upcoming showdown with some werewolves at a sacred site in the area. Eddie wasn't keen on going head to head with them, but there was a very real chance it would come to it.
Eddie's contacts suggested someone that could be useful if push came to shove, but warned him the guy could be a bit of a wild card. Eddie got word he could meet the guy at a particular diner... any time. It sounded crazy, but the world is full of crazy.
Eddie stops by the diner that night. It is empty save for three people. Eddie eats his meal and decides to split. When he asks for the bill, the waitress says its already been paid for by the guy at the booth at the end.
Eddie looks over and really takes in the man for the first time. He's an African-American gentleman eating a slice of pie. He slides a notepad to the far side of the table from him as Eddie comes over. On the pad is a drawing of Eddie showing up at the diner that night. The catch? The drawing was dated two weeks ago.
The individual introduced himself as Sam and asked what Eddie needed. Eddie is disturbed, but resolute. He asks for Sam's help on a hunt. Sam agrees.
Things do wind up going sideways with the werewolves. A couple of Eddie's raw recruits wind up dead. The only reason the rest didn't (and possibly Eddie as well) was because of Sam. Things got real bloody and in the midst of it, Sam wasn't just human anymore. What he was is something Eddie sure doesn't know.
Eddie cut his losses in the area in the aftermath of that night and got out while the getting was good. Sam didn't seem to either notice or care.
