These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: Is Nikolai Orelov a sympathetic defector of the Assassins who is unjustly persecuted or a paranoid man who selfishly takes a First Civilization artifact for personal use and receives a message from that he refuses to pass on to his brothers and whose subsequent self-destructive actions end up fracturing the very family he wanted to protect and likely inflicted a heap of psychological abuse to his son Innokenti.
The Assassins while harder edged and certainly a little Jerkish do keep their end of the bargain up. Nikolai tells Innokenti that they lie when they say that they have protected his wife and daughter while the Assassins say that "they protect their own" but we see Nadya at the end, still wearing that splinter of Rasputin that he tried to hide. In the end it's a massive Poor Communication Kills and Nikolai has his share of the blame.
Crowning Moment of Funny: After touring the very white Assassin compound with Hannah, Daniel meets Paul, the African-American leader of the cell, and quips, "Finally, something that isn't white."
What Could Have Been: The writers initially wanted to have Desmond Miles from the main games as Nikolai's descendant.
The Woobie: Daniel could qualify. First he gets kidnapped as a child from his adoptive family and subjected to all kinds of experiments. Then he gets thrown out into the wild, and even when he makes it back to civilization, his life isn't very pretty with his hallucinations that keep coming and going, not to mention his problem with drugs and alcohol. Then the Assassins take him in, and he makes it his life's mission to meet the Mentor. And when he does? The brainwashing inflicted on him long ago kicks in, forcing him to commit an act that irrevocably alienates him from his new family. He may be Desmond's Evil Counterpart, but not by his own choice, which makes it very hard not to feel sorry for him.
