I'm so confused to the point I didn't know if I should put a spoiler tag or not.

As we all know, in NeoTokyo level, Ghost is seen chasing a hacker girl from a hacker gang in a train car. Her gang leader shows up and starts an unfair fight between Ghost and her guards. At the end of their martial arts fight, Ghost gets knocked in the back of his head and blacks out on the floor. *screen fades*

Later, the actual level starts as you (ghost) standing at some kind of a train station/stop point. And the hacker girl Ghost was just fighting moments before the level starts, is seen walking away from your spawn point not aware of your presence (until she detcts you). you stalk and follow her to the gang hideout.

Now what I'm asking, what has exactly happened between the in-train fight and Ghost starting to stalk the hacker girl. Did Sadako the gang leader forget about him and let him walk away? if so, then why does she fight you at the end of the level? is the hacker girl suffering from Alzheimer? Why didn't the gang deliever Ghost while he was knocked out to the police since they were framing him for a crime he didn't commit?

I'm so confused here and in need of explanation to this plothole.
