He wants to share identity of his dad

"Mom, you are my mother but Reed is not my real father."

Franklin's revelation hung in the air like a challenge, each word cutting through the silence with the precision of a scalpel. Susan's eyes narrowed, her mind racing with the implications of his statement. "Explain yourself," she demanded, her voice steady but laced with an undercurrent of tension. Franklin sighed, the weight of his words evident in the slump of his shoulders. "Galactus invaded Earth 40 years from now and I was the only one strong enough to face him. I used my strength to get rid of him but got seriously injured in the process. Only my parents could have helped me. You had passed away 10 years back and when Reed tried to help me, it failed. We did a DNA test and found that you were my mother, Susan," he began, his voice measured, "but Reed was not my father. "

Sue's hands trembled slightly as she processed the DNA results against Reed's DNA, the screen glowing with irrefutable evidence: Franklin's DNA matched his own. The room fell silent, the weight of this revelation pressing down on them all. Sue's eyes met his, as she understood what this meant. She wanted to refute this but the results were in front of them. Franklin informs her that he must be born to prevent Earth from being destroyed by Galactus. And there is only one way for him to be born with her DNA and his own DNA. She is in dilemma on whether to try to change history and risk Earth's destruction or to let the same history repeat itself.
