It is so sad Adam has never been in medieval relationship. How much chains and whipping he is going to need in order to be cured...
That said I kind of see that ESI's have lots of hidden aggression and they obviously need to release it. It is written on their bodies. You can sense that tension. It is bit like an axe murderer without an axe. It is not aggression what you pick from beta ST's but they give really sinister vibes.
