This is the second role reversal story on the boards right now, though yours is different from Sunrei's Above Alt Else. Your story, like hers, is adorable. I'm just going to quote one thing, and that is the ending:
“You're so strong, Clark. I never understood just how strong until now.”
A strangled half-laugh escaped him at that, and he quickly shook his head. “I'm really not.”
“You are. You went through so much without having anyone there for you. And now you're forced to watch me do what you're supposed to be doing, what you were meant to do, and you're still the one who has to be strong enough for both of us.”
“God, Lois.” He paused to look down at her in utter amazement. “It was never me. Every ounce of strength I ever had, it was always you. You were the one who enabled me to be Superman - not because you gave me the idea for the costume, but because you believed in me. Sometimes the only way I could make myself face the world again is because you were in it. Everything I've done and everything I am is because of you. You were always the strong one.”
She was suddenly clinging to him again, and this time he wasn't sure if she was crying or laughing, but her next words filled him with hope that everything would be OK.
“We'll just have to be strong enough for each other from now on, then.”
Wonderful!
