Here's what I thought we knew:
- the man that raised Keen was not her dad
- Keen's real name is Masha Rostova, and Katarine Rostova is her mom
- a man named Red Reddington is her dad
- we THOUGHT James Spader's character was Red Reddington
- we found bones that belong to Red Reddington
- we found out James Spader is really Ilya Koslov, an associate/childhood friend/lover of Katarina Rostova, Keen's mom, who is impersonating Red Reddington to get the money that was "given" him as part of a government scheme, and the money is to help Keen/Masha.
BUT.... in this recent season, Rostova is torturing "Ilya Koslov" and doesn't seem to know what's what, which implies that "Red"/"Ilya"/Spader is lying, again.
I suppose that's the big mystery, and I'm supposed to be confused, but since I don't like the Katarina character, or the actress that plays her, it's infuriating. Plus, Keen is the worst FBI agent ever.
