Blake noticed something important.

It was at that point that Blake was given a clear look at the backside of Yang's 'outfit'... including her actual backside. During the prior clash with the grimm, one of them managed to swipe at Yang, and while it didn't cause serious injury to her body, her clothes were another story entirely. Although the improvised miniskirt was still holding strong, it was obvious that a large chunk of cloth had been torn away from the section covering the blondes rear end. Combined with further tearing from the unnoticed hole in her panties, it left her more exposed than before whilst still completely oblivious to the issue. The entire right-half of her ass was now in full view.

Blake chuckled into her hand softly, finding some amusement in Yang's worsening situation and utter lack of awareness concerning it. Still, the blonde was now her partner for the duration of their stay at Beacon, and as such it was her duty to render assistance to the girl despite her curiosity to see just how much worse things might go.

"Uh, Yang?" she cleared her throat softly, gaining Yang’s attention all while her own remained fixed on her partner's exposed buttock. "About your... outfit."

Half-turning to look at Blake with an aggrieved expression and her hands on her hips, Yang released a loud sigh. "Blake, before you say anything else, I can assure you that I am wholly aware of the state of my clothes. I have been aware for some time now. It has annoyed me for some time now. In the interest of not souring the start of our partnership with me being in a mood more foul than it currently is, can I ask that you do not bring up my dressing until initiation is over?"

Blake really felt like Yang should have the massive gap in her defenses be brought to attention, but the look on the blondes face was practically begging for her to drop the subject.

"But-"

"Please?" Yang immediately interrupted. "I wanna finish this up quickly and put this whole fiasco behind me."

It took a bit of restraint on her part to not giggle at the irony of Yang's wording, however Blake raised her hands in defeat, conceding to her partners request. "If you say so."

Giving the black-haired girl a smirk and a thumbs up, Yang continued taking the lead. "Thanks partner!"

And with that agreement, Blake had now washed her hands of any current or future wardrobe complications that befall the blonde. Perhaps Yang was aware of her vulnerability and simply wanted to move past it quickly. Blake decided to trust her partner and remain quiet about the situation. If Yang felt the need to flash half her ass to all and sundry, that was her personal choice to make.
