@Wolvenworks it looks like she was stabbed but for all we know she probably has some sort of plating/leather there to protect from shots/stab wounds. I'd assume an assassin would take that precaution as well.
@ZeeZle yeah but look how deep it went. so either the knife snapped or missed her (went past the side) because if she was using some stab-proof armor you'd see more of that blade from it not being able to penetrate the armor
People, the knife looks that far in because it needs to be threatening, but the only way to reach anything damaging is to go between her natural defenses, basically the knife is sandwiched.
@Wolvenworks looking at what she was holding it's apparently one of those razor with snap off blades for box cutting. Possibly only some of the blade is out.
