She shares a close bond with her father, and showed up to see him at work in Chicken, Dynamite, Chainsaw. Antonio was angered when he found out she'd come to see him all by herself. However, he was equally upset when he found out that Eva only came because their parents had been fighting over the phone and Eva heard it and thought she wouldn't be able to see him again. He hugged her and told her that her, Diego and him would never be apart from each other.
She is mentioned again throughout the series by Antonio, who often mentions her age and how she's doing at school at work but is not seen again.
