The depiction does deserve credit where credit is due in one major area. The overall portrayal of when and how Lorna uses violence in Prisoner of X was the best I have seen in the comics since Austen. Yost's Lorna and PAD's second run Lorna had moments where they got it right and wrong. In the case of PAD's Lorna it often veered into a kind of uncontrolled unthinking instability. In Magneto Last Days and X-Men Blue Lorna simply lacked her edge when it came to using force and had too much a conventional super hero take on the character and her views.
However, due to the nature of the events in question we don't know if her depiction here will have any impact going forward. I will only say it is good to see a writer get it right in terms of Lorna's willingness to bring down the hammer. I know full well it can only happen on occasion and its easier with what are later reveled to be mental constructs then with say Purifiers. But, writers have gotten it so far off in the comics for so long (between veering into green haired Jean land or blind mentally unstable girl land) its positive to see a series that managed to come pretty close to the bullseye in that area for the character.
