Leia nodded a few times. She almost apologized but also didn't feel like she had anything to apologize for. Except maybe that it was kept as a secret and she was telling him now. "It was something we both needed at the time," she admitted quietly. Her thoughts drifted back to the few short months that Kes visited her now and again on Hosnian Prime. They enjoyed each other's company, and each other, whether just as friends or as lovers. It was unfortunate that their choices led to a rift between them when she found out she was pregnant.
"I ended it," she said a moment later. "Your father disagreed, especially once I found out I was pregnant, but - I ended it." She didn't know if that was going to change Poe's opinion of either her or of his father. "He did come back after the kidnapping, though we weren't able to find her." And Leia's shame was how she treated him then, with accusations flung out of heartbreak and worry over losing her daughter.
She touched the side of her hair and looked at him. "I know Rey is excited to have a brother," she said. "And I hope this won't change your opinion of her in any way except for the better." She didn't mention that she also hoped it didn't change his opinion of her too.
