In the video titled something like Raymond reddington and the woman he loves. Katarinas effigy responded to Raymond’s comment “ther were two and I could only save one “ obviously he chose Elizabeth and katarinas character responded “ you made the right choice.” I think that meant he had to choose between the two of them. If he were referring to the supposed real reddington than the bones would probably have been scorched beyond recognition. Yet when Raymond is disposing the bones they don’t look burnt
In season 8 we have the final memories of Liz from the night of the fire. I think they are very important haven’t received enough fan attention. Ilya and Katarina have saved Reddington from the fire, and placed him in the car. Ilya is now in the front seat, Liz/Masha and Katarina are in the back seat with him. Next Masha remembers her stuffed animal and runs into the house to get it. Katarina calls out to her to stop, Ilya tells Kat not to worry he’ll go get her. Next we see Masha being led out from the fire by a man as the fire surges all around them. I think Ilya/imposter was burned saving Masha. That’s when they both got scarred. The real Reddington didn’t survive his wounds. Katarina was never burned (eliminates those who want imposter to be a female) which I think is nuts. In the season of the bones we are led to think they are Reddington’s, but could they have been Katarina’s as Ilya finally killed her for Marsha’s and his own safety? Dembe says to imposter (Liz’s) Reddington, I don’t know if Elizabeth can ever forgive you for what you did to her mother. I think Katarina the ghost is dead.
