Wait, WHAT? In her original introduction she was virtually-mute, spaced out, and barely even seemed to be aware of half of what was happening around her. Her VERY FIRST PANEL was a PTSD vacant stare at a blinking "No Vacancy" sign:
You could literally count the amount of frames she had actual dialogue in ALL FOUR ISSUES of NYX she appeared in on one hand (and that's not exaggeration. She had maybe FIVE lines of dialogue in the entire series).
In her next appearances under Claremont she was damn near feral, snarling and growling at pretty much everyone. And still rarely speaking actual words (the closest to ANXM she acted was aping Psylocke's mannerisms in the background, which has since been accepted as wholly OOC). Under Kyle and Yost she was reserved and quiet, and when she did speak it wasn't at length. Liu ramped it up to eleven to full-blown Robo-Laura (even under Kyle and Yost she used contractions). At NO point under KYost or Liu did she EVER tell someone "I'll get all stabby." Hell, even in Avengers Arena (also by Hopeless, so he SHOULD know better) she doesn't put together more than a few words at a time; she ambushes Cammi, takes a sniff, and her response is pretty much just "Sorry, it wasn't you," before walking off without a word of explanation.
The one and only writer Hopeless's characterization in ANXM is anything REMOTELY like has been Bendis. It sure as hell isn't how she's always been portrayed.
