"You already saw the twins? The saw you?" Mary's heart is beating too fast from the sudden news.
She is not worried about what Arion feels, but she is worried about what her twins' feel when they saw their father. She knows what her son really feels towards Arion. And she's afraid of the words that he said to Arion.
Aaron will most likely to say something that will hurt Arion and will hurt himself.
"It's my fault, Mary," Leonardo spoke. He told Mary that he used Arion's rescue mission and the twins' mission for them to meet. Leonardo apologized to Mary that he hid the truth from her and that he has no intention of hurting her feelings. He just wanted the twins to meet their father first. "Originally, I wanted you to know about Arion when the twins make their report to you. However, I didn't expect Arion to show himself to you right away."
