Lina Wilson was also surprised by the news, as Bella Scott's situation was the worst. Other hypnotists were reluctant to treat Bella because her hypnosis methods were different from theirs.
She never thought that Bella would have such a strong reaction to the stimulus and be able to break the hypnosis on her own and recover her memory.
The painful past of Bella Scott was due to Edward Anderson back then. Bella chose to forget her feelings for Edward and asked Lina to implant a false memory of Edward being a heartless playboy into her mind.
Now, it was Edward who enabled Bella to break through the shackles of her memory, which made sense.
In short, Edward Anderson was the medium for Lina to hypnotize Bella.
Before arriving at the hospital, Lina specifically called Snow Collins and told him about Bella's situation.
She probably knew what decision Snow Collins would make, but if so, Snow's plan to completely separate Bella from Edward would likely fail.
