Blake revealed herself in front of White Fang members in the end of volume 1. Not only did she take her bow off, she also addressed the White Fang members as "Brothers of the White Fang." This made it pretty obvious that she is, or more likely was, a member of the White Fang.

He probably asked about her to various veteran White Fang members afterward.
