everytime I hear Sergei saying that he's been given a job to do and [to claire] to answer the question that's been told to ask I squirm because I imagine that, as the proper right-hand man he is, he follows every word that comes from Vladimir's mouth.

now, atm, I really would like to see Sergei getting off from torturing someone while remembering what vlad told him to do, how he described to him the whole process, like, while Vlad is talking he walks around Sergei and explain in detail the fear that the victim should feel, the moves and how to balance the patience & violence, etc. Vladimir touches and brushes again Sergei to keep him focused on the task, but Sergei is overwhelmed by the heat that it gives him and, something among those lines, hope you get the idea because I don't know how to put this into words

even one-sided Sergei -> Vladimir is okay (more angst = more cookies)
