So I wrote this to fill in a moment that DBZ doesn't show us in either the manga or the anime. This is from the scene on the Lookout where Goku reveals what happened to Gohan and Vegeta.

"Where are my sons, Goku?" asked Chichi.

"And what about Trunks and Vegeta?" asked Bulma.

On the Lookout, everyone stared at me. Awaiting answers. Piccolo knew, turning his face away.

When I woke up in the wasteland after Vegeta knocked me out, my heart sank when I realized I couldn't sense him. Or Gohan. Not being able to sense someone only meant one thing.

"Go on, Goku," was Krillin's quiet murmur of encouragement behind me.

It was up to me to tell them what happened.

I held Chichi's gaze and said, "Goten and Trunks are both safe inside the Lookout. But… Gohan and Vegeta are dead. Majin Buu took them both."

Chichi's mouth fell open and her face went white. It came as no surprise when her eyes rolled up in her head and she fell backward, hitting the cold hard tile of the Lookout with a soft thud.

I gasped and ran to Chichi's side as Bulma let out an agonized scream and lifted Chichi up, her head lulling onto my shoulder, her body limp.

"Got her?" asked Ox King, choking back tears.

I nodded and murmured, "Yeah. I got her."

Ox King followed me into the main building. Inside, I found a bedroom with a small daybed that was exactly what Chichi needed and got her settled and comfortable. I frowned at the tear rolling down her cheek and wiped it away. Not really even conscious and already crying for her son.

I sighed. Somehow, the realization that I'd see Gohan up there in Other World with a halo over his head wasn't all that comforting and I was dead! I was almost out of time on Earth as it was—my body feeling weirdly heavy and tired.

Chichi still had Goten and she still had her father but she needed Gohan, too.

I lightly rested my hand on hers and whispered, "I'm so sorry, Chichi."

She groaned and stirred a little, her fingers wrapping around mine.

"Goku…" she choked, eyes half open and lower lip quivering.

A slight ache wormed its way into my chest.

I kneeled in front of her. "Hey. No tears, Chichi. I'll set everything right. Gohan will come back to you. I promise. Okay?"

I brushed another tear off her cheek as she sniffled and nodded.

I gave her a small smile and her hand a gentle squeeze. "Now get some rest, Chi. You need it."

Her eyes drifted closed.

I smoothed a loose strand of hair back away from her face and lingered at her bedside just a few more seconds before leaving the room. At the doorway, I found Ox King quietly watching me. He held my gaze for a long moment before heading inside where Chichi rested.

It was time to go wake up Goten and Trunks and teach them a new technique. Majin Buu would pay dearly for what he did.
