Some AUs, I freely grant, are nothing more than a jolly game of 'what if', but I do think there is a genuine remedial intent underlying some of the more frequently reworked incidents.
Err, of course I shouldn't mention it, but...for a story written with a clearly remedial intent, referring to Shadow (an episode that has been discussed here lately), see "A Place of Greater Safety," on Shirley Jacob's Classic SciFi & Cult TV site (http:..www.ess-jay.org.uk/scifi). Unlike many stories by the same author, this one is G-rated and family-friendly (literally, this time).
