Perhaps it's also the right time to neutralize an opinion which surfaces from time to time, and was already several times denied by the Dev: that Edwin watches the videos of Victoria for his sexual gratification. Especially the very first scene is quite (purposefully) ambigous in this regard, with him sitting in the dark, half-naked. It's is not idiotic to assume he is jerking off, at a first glance, but i'd like to counter this with material from the scene itself, to show it's worthwhile to take a second look at nearly every scene.
As we can see both hands are unused on the chairs armrests. He is also able to answer the door almost immediatley, there is no "Just a second, please." Yet, this is not 100%, since we don't see both hands at the same time. But we have another example of the setup of his wanking session and what is his go for:
right hand worker, obviously. Prefers to have toilet roll in comfortable reach on the left side and likes to watch slightly fantasy themed lesbian porn, which seem to be as far away as possible from his Mothers porn settings, both in bodytypes of the actresses and the theme, which is not a reality type. While not ultimatively conclusive, it suggests that the introduction scene was more likely not a wanking session. I can't completely rule out, that there may be a level of excitement and arousal on a very basic and animalistic level, like anyone can encounter when they are exposed to sexual images, but i don't think he ever wanted or needed to act out on this, quite the opposite.
Probably he gets more annoyed by it than he already was.
