Let me reveal the truth behind Bogdanoffs and give you your final bogpill even if you didn't ask for it:

Bogdanoff = Бoгдaнoв
It's a common slavic name (in their case through their Bulgarian origin) meaning "God-given" (bog-dan)
God-given = Deus Ex
They are two identical clones
They have augmentations in their head
Illuminati fear them
Bulgarian blood gives them +5 lockpicking skill

Now, it all comes together, just connect the dots
