After so long apart, Bulma looked much better when she saw Son Gohan return, and she held him by the hand as she told him everything that had happened over the years. Son Gohan had been dead for thirteen years, and there was far too much he did not understand about how Earth had changed, so he listened carefully.
Bulma smiled and slowly recounted what had happened over the years.
From the development of the Time Machine, to Trunks taking the special medicine for Viral Heart Disease and traveling to the past in the Time Machine, then bringing Bulla, Luo Fei, and the Askari siblings over—she explained it all in great detail.
Son Gohan listened seriously, nodding from time to time.
When he learned that Bulma had successfully created the Time Machine in order to save the world, admiration showed on his face. When he heard that, after his death, Trunks had inherited his will and continued fighting the Androids, nearly dying several times, Son Gohan's heart clenched, and then he nodded with relief.
When he heard that in another world, he did not exist, but there was a girl named Bulla, his expression went slightly blank, and he felt a little emotional.
"...After Trunks went to the past, he discovered that it was a world completely different from ours."
"There were warriors even stronger than the ones here, and Earth was supported by the Saiyans as well. Fortunately, because of that, our world was able to be saved. Trunks trained with my brother-in-law in the Hyperbolic Time Chamber, and his strength improved tremendously."
As she said this, a trace of pride appeared on Bulma's face.
Son Gohan had not expected there to be so many twists and turns in between. After listening, he cast a grateful look toward Roland.
