Here are the 'facts', and what can be deduced from the internet:

It appeared in Castanedas book Art of Dreaming [CC book 9] and there is a 'real life' little girl who have been presented as the 'Blue Scout' and who have been participating in some of the Tensegrity meetings somehow. The Blue Scout-girl seems to have choosen to leave the Castaneda team, according to what can be read on the net.

The subject of 'Scouts', belongs to the realm of Dreaming.
