Thanks for the ask, my friend!!!
13. What color do they think they look best in? Do they actually look best in that color? I've actually tried to check what colour she looks best in. It seems to be blue and violet, or white and gold. She also really looks good in red and yellow. As for what she thinks she looks good in, she thinks she looks good in red, silver, gold, and blue. She's mostly right on this. Curunarí has an okay sense of fashion.
34. How hard is it for them to shake a sense of guilt? Awfully. Curunarí feels guilty about things she's not even responsible for. She never really shook off her sense of guilt, not until she decided to sail West with Celeborn and Cirdan. She feels guilty for a lot of things including Melkor’s crimes, her brothers’ her crimes, her mother’s crimes, Sauron’s crimes, Turgon’s stubbornness, the Third Kinslaying, and the sinking of Beleriand. She has nothing to do with these things but she feels responsible for them. She even feels guilty about existing sometimes. So yeah, guilt and Curunarí are in a long-term relationship.
38. What memory do they revisit the most often? She often thinks back to the moment she fell in love with Celebrimbor. They were already parents by then and she had just given birth to their first son. It was dark and the tent still smelled of blood. But there stood Celebrimbor, exhausted but happy, rocking their little boy as he fed him with a bottle. Telpelen fussed but Celebrimbor sang to him. That was the moment she fell head over heels for him.
