Did Raymond Reddington lie to Liz about not being her father?

As far as I have seen (Just started S07), no one has bothered to do a DNA comparison between Jennifer and Elizabeth, which would be an easy way to confirm blood relation. If they aren't related (Reddington isn't the father of both) then it could be inferred that Koslov assumed Reddington's Identity and fathered Jennifer after 1990.

However, given the fact that "Reddington" has spent 30 years building an empire to protect both himself and Elizabeth while also working with the FBI for the last 7 years AND that he seems to know things that only Reddington would/could know, I believe that the real Reddington and Koslov conspired to hide Elizabeth from Katarina while the latter was in the middle of burning her identity. The lie created by Reddington and "Reddington" was sufficient enough to convince Dom that the former had died and the latter had assumed the former, but the apparent reality (thus far) is that Koslov and Reddington recognized the danger Katarina presented to everyone and went on the lamb hiding Elizabeth in the process.

The hitch to the story that Dom gave Liz is that the accounts that Reddington had set up in his name would have been watched for activity by ALL parties (CIA, FBI, KGB/FSB) given the sensitivity of the situation with Katarina & Reddington; the kinds of crimes that were alleged at the time are the kinds of things that Governments pull out all the stops for. I believe that Katarina doctored up a cutout to gain access to the money so she could disappear.

As for the bones from Mr. Kaplan, the notion that Reddington/"Reddington" couldn't gain access to the database housing that information and substitute it for w/e he or they wanted is cute if not a little naïve.

TBH, the whole plot at this point is rapidly approaching the muddled convolution so whatever answer they give at the end is going to be superbly underwhelming. Why? It's a TV show for which the plot they wrote spanned only two seasons and have been simply expanding that story instead of having actually written the subplot (Red/Katarina) when they wrote the original plot. For a good example of hamhocked plot mending, you only have to look at the last season or two of Lost.

I mean, come on, Elizabeth has literally spent the last six years watching over both shoulders and yet trusts this new neighbor, and older woman no less, with her child which she just got back after having spent two years hiding her. And no one bothers to ask Liz about who's watching Agnes, least of all Red?

I believe that Raymond is Katarina Rostova, Liz's mother. I don't want it to be true, but the following points support this theory:

• He is not the real Raymond as seen in the show.
• Raymond changed his identity using the surgent show in the previous seasons.
• Katarina is still a mystery.
• It makes sense that Raymond was Katarina and she changed her identity to be Raymond to leverage his power in not getting killed and to be able to protect Liz.

I believe that red the imposter red is her father, because he was the one that saved liz from the fire, remember liz has that burn on her hand, and red has his body burned from saving her, remember..he might not be the real reddington but he is liz father.
