We know that the experiments done on Jessica can potentially lead to psychological issues, notably in the case of
who exhibited severe anger management issues or even dissociative episodes.
The "Whizzer" also had psychological issues, which could possibly be attributed to the treatment, too.
Jessica occasionally seems to have some anger management problems (see: her court-ordered sessions).
She also is apparently dependent on alcohol, and even has started experiencing some hallucinations when under great stress.
On the other hand, we know Jessica has PTSD, of which alcoholism and even hallucinations can be symptoms. And her anger could just be normal for someone who has so much to deal with.
Does Jessica exhibit any psychological effects (not necessarily anger issues) from the experimental treatment used on her? Or can it all be attributed to her individual experiences?
