the backpack kinda shot that down for me. I mean you see that her dress is in the way, and the way the swords fold to fit inside that tiny pack is more believable than Stormflower ever was. In fact even now I'm still inclined to believe the swords were in the backpack.

Really though, the twist was kind of blown too early; everyone called Blake, but they were still fired up when the reveal happened because it had huge implications for the plot (Weiss, the White Fang, and other things). In this case it felt kinda dissapointing because there doesen't seem to be any obvious continuation or consequence to this.
