Introverted Aggressors have this aura of solidity, they look very contained (and to a certain extent hard to approach themselves) and observe you for a long time before getting into "attack mode". They like more games of sexual tension than extroverted ones, who are fairly straightforward in their approach. With ES_Ps there's hardly anything unpredictable, you usually know from second 2 when they want to get you and they will just pursue you instinctively. It's as if they don't need to process much of the whole interaction, they just react to immediate stimuli.
