This was a short (?) Gen, pre-series, Dark Angel crossover fic featuring teen Dean. I think it may have been an outsider POV too.
All I remember is one scene where a woman who works for Manticore is mugged in an alleyway and teen Dean comes to her rescue. Dean ends up with a superficial injury, a cut lip or something like that and the woman dabs the wound dry with a hanky.
Dean is modest and kind to her and then goes on his way. When she returns to work the woman remembers how brave Dean was and replaces the DNA Template of one of the proposed X5's with Deans DNA.
I loved they way the author spliced the two fandoms together and would really like to read it again.
Can anyone point me in the right direction or give me an author or story name?
Fingers crossed and many thanks.
