In "Epistatis" we have a theme quite common in the literature and theater: the invasion of someone into the lives of two others and the situations that inevitably arise between the three. And all three characters are shapeless and try through the language of memory to shape a past that may help them navigate their uncertain future.

In "Those Years" the same theme is repeated: in the middle-class tranquility of a couple, a common friend from the past invades, this past conquers the present and determines the future, which will be eroded by the possibility of chance repetitions.
