When I met Marcelo Pitrola as part of our Author Spotlight series last September, he mentioned he was working on a new project: a collaboration with longtime artistic partner Silvia Hilario and actress Emilse Diaz.
‘Diario de incertidumbre’, which premiered on 5th May and is excerpted in an exclusive English translation here, is an eerie tale about a woman caught in a hospital with a mysterious ailment. As she waits for a diagnosis, she re-lives and then re-evaluates her life, falling further and further away from certainty as the double examination progresses.

The play stars Emilse Diaz as the troubled woman at the center of the story, and Silvia Hilario as both doctor and nurse.
I was captivated by the idea of what is essentially a one-woman play: how would such a thing evolve onstage? How would her memories manifest? How would an actress perform under such obscured conditions? How would a stage director use an atmosphere as cold as a hospital ward to convey so many shades of emotion?
I met up with Marcelo, Silvia and Emilise to discuss the work, the collaborative process, and the creative constraints of portraying an entire life in a single clinic room.
How did you get the idea for ‘Diario’?
Marcelo: Silvia proposed the core image of the story. Afterwards, I began to sort through my own thoughts and questions regarding the different women, selecting here and there in my attempt to construct Diana and her world. I began to write the interior monologue that serves as the linchpin of the play, and the idea of a private diary immediately appeared as the ideal medium.
Silvia: The idea was based on my own experience. I’d had an accident – I was that helpless patient. I wanted to capture that feeling of stasis, of confusion.
Marcelo and I started with the central vision of the woman under diagnosis, and he gave it dramatic form. He invented the mythology of Diana’s life – the ballet teacher, the absent father – and came up with the idea of the acts. It was a very comfortable collaboration and it’s been wonderful to work with him.
Marcelo: Theatre is a collective, collaborative activity. Effective dialogue produces the best work. Silvia is a good friend and she’d already performed as the protagonist in my earlier play, ‘The Peronist Princess’. We’ve always had an excellent rapport, and we have similar ideas about what aspects of theatre are most appealing. I suppose that’s why she approached me with this idea.
And how was it, Emilse, to come into this process as an actress?
Emilse: I have to confess that it was difficult in the beginning, wondering how to convey all of this. The actress is trapped in a single room. She’s always in the bed, but she’s also always moving, changing, transitioning into different states. She’s running back over every minute of her life. It’s exhausting. But in the end, I very much enjoyed the process – the diverse possibilities. It was a game. It was gratifying.
Marcelo, you’ve written many works about women and womanhood – what was it like to develop this specific female protagonist?
Marcelo: I do seem to have more of an interest in female characters than in male ones. That may be because I have questions about the feminine sphere, and I write in order to answer them.
In this work, as well as in ‘The Peronist Princess’, I wasn’t really sure where the process would lead – I just had a series of questions, and they were pushing me to write more and more. That’s basically how it was all conceived.
And as women, how did you two, Emilse and Silvia, develop this female thematic?
Emilse: There is, well, an excess of women!
Silvia: Yes, but there’s an important theme about the relationship between femininity and fertility – what you can make out of yourself. The character of the nurse: she became a mother at 16. She didn’t question it; it wasn’t an existential dilemma. The doctor is another alternative: she has a different attitude. And Diana’s mother, too, represents a different set of obligations – a kind of pressure for Diana to define herself against. And then there’s Diana’s friend, yet another version of womanhood. She’s made different choices too – she has different impulses. Altogether, they form a kind of synthesis.
The synthesis that Diana doesn’t contain within herself?
Emilse: I think she feels profoundly alone. In this place, in the hospital, you feel isolated. Naked.

Can you tell me a little bit more about what it was like to bring this concept to the stage?
Marcelo: I’d say, first of all, it was difficult to convey something as private as a diary in a theatrical medium. It occurred to me that different interlocutors could appear during this internal monologue, to allow it to become more theatrical, more externalized. Piece by piece, the work was transformed into what you could call “mono-dialogues”. The subjectivity – Diana’s universe – came to life.
Emilse: Yes, and for me, the problem was performing such an internal transformation. How do you act that out? I was also working with a character who doesn’t have a sense of herself. She is what other people call her – she speaks a great deal about what they say about her. And of course, as a patient, she is what the doctor and nurse say she is. All of her traits have this feeling of externality – as thought she exists as a reflection. Her role as a performer is in keeping with all of this. She takes on other roles, and speaks lines written by other people.
But for a work about so many “other people”, it’s very restrained, very narrow. For much of the play, Diana is totally alone.
Silvia: Yes, there’s a restraint in the design that places it firmly in liminal territory: it lacks detail. There’s also a projector that serves as a kind of magic lantern. At first, it’s used to project the radiography slides of the patient’s anarchic body, but then it becomes more complicated than that – less strictly medical.
The stage, the physical dimensions of the theatre, crudeness, unadorned blankness – it’s all very much a part of the design. The cramped little bathroom to one side of the hospital bed is a part of the production space, and the blocking incorporates it into the play. The bed is also ambiguous, deceptively simple, un-identified. It can be seen as a multiplicity of beds. Where you dream, where you wake, where you make love, where you die.
Emilse: In the context of childhood, the bed becomes a place of ‘play’. But then, it’s a sickbed, too: immobility, pain and sickness.
How was sickness given meaning in the play?
Marcelo: Diana’s character is in the clinic because she had an accident. She’s desperate, in extremis. But then, during this period of enforced stillness, she starts thinking about her childhood, her career, her art. She’s been many different kinds of artist: a ballerina, an actress, a choreographer. And now she’s suffering from this disorder. She’s trying to control her body but soon she starts trying to control her life: to regulate her past, define it and all of its components, keep it from destroying her. When she enters the past, it’s as though she enters another space – a kind of limbo.
Silvia: And as she endeavors to find herself, to undertake this journey, she’s interrupted by the nurse and the doctor. The nurse’s realm is quotidian: she’s trying to impose a rhythm, a routine, something more normal than the emerging consciousness of the intractable patient. Meanwhile, the doctor uses scientific discourse, trying to translate all of these feelings and impulses into symptoms. In this way, the three women have little connection with each other.
They seem to be total opposites. Yet the doctor and nurse are both portrayed by the same actress. Why?
Silvia: Well, for one, because of the clear overlap in the roles. They both represent realism. The nurse is pragmatic, bodily. The doctor maintains distance. She is prone to discussing everything in medical terms of either a sickness or a cure. She has an answer for everything, as it were.
Emilse: These three women are all looking for the truth. The doctor is obsessed with concrete, specific objectives – because the alternative is too alarming. The nurse also represents certainty and uncomplicated things. This play is all about complication. The three women aren’t really antagonistic. They’re like facets of one another.
And what becomes of Diana’s relationship to herself, and to the doctor and nurse, at the end of the play?
Silvia: She never solves the problem. She only asks more and more questions. We decided that the material led us there, and that there’s no way to tie things up neatly. She exchanges the firm ground of a decision for ambiguity.
Emilse: We don’t know what she’ll do, but the sensation at the end is that after all of this, this great production, this investigation…she’s finally ready to ask these questions honestly. Who am I? What am I? We don’t get to find out.
