Headcanon: The Gemini (Anastasia and Nikolai)
Hands down they are Lukin's favorites and what he considers the crowning glory of the Department's program. The children of the Winter Soldier and the Black Widow, he expects them to be nothing less than their parents. They were bred and trained to be the perfect spies, a tag team of assassins working perfectly in sync. And he will accept nothing less than that perfection.
But seriously. They are his favorites. His shiny shiny toys. If you think you are his favorite and you are not them, you are wrong.
[It should be noted that Lukin is well aware of Nikolai's over attachment to his sister and that it borders on psychosis. It should also be noted that Lukin encourages it. He wants the twins concentrated on each other and the program with no room for distractions.]
