So going through the prologue, there's a lot of extraneous wording that could be deleted to make things move faster. Like the last sentence of the first paragraph could totally be dismantled with the parts going elsewhere like "The slender figure clothed in black moved through the abandoned buildings. With a skittish look past their thick hood and full backpack, they carefully crossed the road to a dark alley." (here I also fixed a dangling participle where it read as the look itself crossed the street and not the girl)
Notice I also removed 'looking' from 'abandoned looking'. Extra words like this slow the reader's pace getting through the scene. Now if you wanted to get the idea across that the buildings just seemed abandoned but were otherwise occupied, you could say 'silent buildings' instead.
You also use the word 'seemed' a lot. Repetition aside, this also takes away from the reading experience.
"She seemed to just be standing still in the alley" The word 'seem' gives doubt to the true nature of what's happening. But she is standing still, or at least pausing for a moment to evaluate the wall.
"An eerie light came from within the crack, which dimly lit up the alley while the girl seemed to get impatient." I'd think she was impatient, but the 'seem' filters it through a narrative voice that doesn't appear to know.
Then in the next episode, a reader expects to sit in with the protagonist somewhat immediately, especially after a prologue. But instead, we attend a meeting that the protagonist isn't even there for and the meeting is like another mini prologue. The mystery about the unidentified drug might come off better if we hear about it after we sit in with Shane and learn about his new case along with him.
These are just my opinions, so take what you will. But things like this can make a reader stumble or grow distant from what's happening in the story while they read.
EDIT: I'll also add that there is a lot of telling instead of showing. It's most evident with certain passive voice sentences when they could be more active. I scrolled to the latest episode and spotted some.
"There were people walking outside …" could easily be "People strolled outside.
"The area was dimly lit by a few bare lightbulbs …" could be "A few naked lightbulbs hanging outside of the cells barely lit the area."
"Their cuffs were taken off …" could be "The guards uncuffed them …"
