User blog comment:Aeratus/Guide to the Adam Jensen Clone Theory/@comment-178.214.10.194-20171008131823

Eliza part can just be a nod to Adam's memory alteration done by Illuminati. Adam is driven by urges that aren't his, he has memories that aren't his (and that's why she thinks he is inconsistent with the Adam she knew in Panchea). It also links to Harvester side mission. Daria is basically two people in one body because she has implanted memories and urges that aren't truly hers. Jensen is same due to implanted urge to meet Janus and implanted memories (like that from Criminal Past) to make him kill Janus hence "coexist with other versions of ourselves". Given the evidence and context of Black Light that seems to be the case.

Second thing is that Jensen if he is clone wouldn't feel that strange sensations he did in Black Light. Daria knew to some extent that she has implanted killer personality injected in her because she had already estabilished personality before. It also applies to Jensen: he feels that something is not right, that some things he remembers are strange and alien to him though it's not as obvious for him as for Myska due to newer technology (the one used in Daria is at least 4 years old and was probably a prototype).

Third thing is that Jensen was rescued by Elizabeth DuClare' rescue team that forced Page and Everett to stop their search for remnants of Hyron Project before they even started for reasons unknown to them. DuClare works secretly with DeBeers while Page and Everett know nothing about their "arrangements" it seems very unlikely that they would give away his body after year of captivity to Page, It's too suspicious and would blow whole cover of this operation given that Adam is on the official list of Panchea survivors aaaand they both don't trust Page at this point at all.

As for the body: it might be failed attempt of flash cloning Jensen from the material Megan Reed gathered before Human Revolution or an low quality asset that was made hard to see without using 3rd party programs forgotten hence the other crates being empty or maybe it is something that was saved from White Helix Labs (maybe the original donor of Adam's special gene?) given that Vault has various images of lab that is being consumed by fire. The body itself when you look at it with 3rd party program has different facial characteristics than Adam from HR/MD (nose is too big, no hair, skin is darker than Adam's from both games, it has more details like skin having more wrinkles and being rough).

Most of these can be actually interpreted as for supporting the clone theory, yes but the third point is a big contradiction for Versalife having original Adam Jensen in their vaults. It would make major plot point look dumb as hell. The most possible thing is that Page wanted to have the biggest achievement of White Helix (de facto precedessor of Versalife) and Megan surely shared her previous research about Patient X. They just used that DNA sample to create basis for their Orchid/Nanotechnology/whatever research. It doesn't need to be conscious or even alive, it just exists to harvest and/or experiment upon. Why it has similar scars to that of MD Adam? Devs probably being lazy as those characteristics aren't seen without cheating.
