I somehow (jokingly) predicted to a friend that Blake would have a sword-gun-whip as a weapon. And then it was right. Anybody notice that on the trains, the cargo boxes had snowflake emblems on them? Perhaps Weiss is related to it in some form, since her part of Red Like Roses mentions that she's "burdened by a royal test" -- maybe she's royalty, and the family's emblem is the snowflake.
