The truth about Elizabeth Keen...?

Judging by the entries/replies, I don't know if anybody is still getting on here, but I've been pondering things for awhile (since they have given me plenty of time to think!). So, I wanted to share somethings that I have conjured in my head about who Lizzie really is and why Red wanted her. If you find any flaws in this theory or have a different opinion, let me know. I love to debate.

Let me start by saying that I believe (for a long time) that everyone in the unit is on the blacklist. This became more evident to me when Tom told Red over the phone while in Germany "...YOUR task force." That is, everyone except Ressler. But that's another topic.

The idea that Red is Lizzie's father is too apparent now that it would almost be a disappointment to find out that he is. So why Lizzie? Let's start with what we know: Red hired Tom to watch Lizzie; Lizzie's wrist has a burn on it from a fire that is strikingly similar to marks that keep popping up; Lizzie has had the fulcrum and Red wants it; Lizzie's memory has been tampered with (in essence, erased). Spread out over two seasons, these are all just random events. But if you were to combine them...

Season 1 Red kills Lizzie's adoptive father. He proceeds to go outside where he finds Tom who was there to visit his father-in-law. Judging by the conversation they had, Tom had no idea whoop Red was. Scripted to add depth to the storyline? Perhaps. Or maybe at this juncture he didn't and Red hasn't procured his services.

What we do know about Lizzie is that she is young, fresh into the FBI and new to the profiler job. We also know her father died and she was taken in by the afore mentioned man. But what if her memories of the fire are fiction? The scar on her wrist is large. If it had happened as a child, it would have stretched as her body grew, making it nearly invisible as an adult. So where did it come from?

I say all of this to end with my theory; Lizzie was a [the] Major recruit. Her last mission was to retrieve the fulcrum (probably with Tom). The mission nearly ended due to a fire where she was "branded". Although it ended up being a success, in order to keep it safe and out of someone else's hands (probably Red's), she had her memories altered (as the doctor had mentioned at the end of Luther Braxton Part II). Tom was sent to watch over her by the Major. Red seized an opportunity claiming that probably she was his daughter.

Now, if this were to be the case, that would probably put Lizzie at #1 on the blacklist.
