"Katara?" Aang knocked on the door tentatively. "Can I come in?" After moments of silence, he decided to go in anyway.
Katara was laying on the bed, staring at the celling with one hand placed on her stomach. Aang sat on the bed next to her.
"Jingbo left. Zuko said to tell you goodbye. The kids are in bed, sound asleep."
Katara turned to Aang and smiled.
"Thank you."
"Don't worry about it." He placed his hand next to Katara's on her stomach. The arrow on his hand glowed for a moment, as it did whenever he touched Katara's belly when she was pregnant.
"I'm sorry about everything I said, Aang. You're a great father and I'm so glad to have you when I do. We knew going into our life together that it would always be hard and I'm sorry for getting upset." Katara sighed.
"I should be the one apologizing. Jingbo never should have said anything about us needing to have more children and I should have never agreed with him. I cannot imagine how hard it must be to carry around another person's weight inside of you."
Katara chuckled. "Well, it certainly isn't easy."
Aang lied down next to Katara and snaked his fingers through hers.
"Remember when we were trapped in the Cave of Two Lovers together?" Aang said.
"Mhm."
"And you asked if we should kiss?"
"I remember."
"Well, just thinking about kissing you made me feel weak. As if all the life had been sucked out of me. I was so weakened at the thought that I couldn't bear to think about it, ever. But when we actually kissed in that cave, I felt this surge of energy in my soul, more powerful then when I redirect lightning inside of me."
She turned to look at him. "Wow."
"I felt that whenever I was around you after that. And I want to feel that way for the rest of my life."
Tears filled Katara's eyes as she slowly kissed Aang, feeling the same energy that he explained. It coursed from her toes to her fingernails, making her shiver, yet feel warm as ever. And it was perfect.
"I love you, Katara."
