Zolnir Qrow and other faculty members are probably aware of her Sembalance and the reason you are suprised that nobody found out is because it's convienent for Ruby's jumble of words for Yang's exposition. Forced or not it doesn’t chage the fact that it’s now woven into canon that Blake needed to be informed about Yangs semblance, and as such now needs to make sense…or at least I would greatly appreciate it if it did. My suggestion, that Blake hasn’t bonded to well with her own partner, allows this scene to flow naturally, and seems to coincide with Arryn mentioning that Blake is getting a little obsessed with stopping Roman, while having the side effect of shooting down the Bumblebee ship a peg but eh, sacrifices need to be made for the plot.
