I’ve been ruminating on two things I heard or read some time ago.
The first was when Exectutive Producer Bokenkamp posed the question, ‘Who would be most invested in a child’.
The other is the constant message that Lizzie would never be able to forgive Reddington if she knew the truth.
To the first, the obvious answer would be a parent, and Reddington would be that person.
The second question - what would Lizzie never forgive Red for? - isn’t at first obvious. What could be so horrendous? She’s already forgiven him for turning her life upside down, for ruining her marriage (because she was happy to live that lie), for killing her foster father, for impersonating her biological father, for trying to kill her mother, Katarina.
For so many things.
Reddington asks Liz ‘What if everything you’ve come to believe about yourself is a lie.’
Knowing Lizzie as we do now, to find out she never was Masha, that she was used to take Masha’s place in order to protect the real Masha for some reason, that she was put in the path of danger from childhood, and that Reddington had some part in that decision - even though he has watched over her all her life... now THAT would be something Liz would find ultimately unforgivable.
There are probably a thousand holes that would need to be plugged for this to work and I haven’t tried to find them or plug them, but it’s an interesting thought.
