Author Notes:

Unfortunately I think there are a few inconsistencies with the ages of Gosen, Gohan, and Androids 17 and 18. When I was thinking about this story, I didn't exactly keep track of ages, which can really mess up my story. So, after DAYS of thinking, here is the explanation.

Gosen is not only from the Mirai Timeline, but his timeline is also an alternate reality. Gosen is Gohan's twin brother within that alternate reality. The massacre happened ONE year ago in Gosen's universe. But in the present time, that massacre will happen THREE years later. Meaning there is a gap between the time Gosen and Trunks come to the alternative past and when that massacre happened.

Gosen and Gohan in that alternate reality would be 13 by the time the massacre happened. One year passed since then, so now Gosen is 14. Since he came to the PAST , it means Gohan is 10, while Gosen is 14. Gosen had a twin in Gohan in the MIRAI timeline, but not the PRESENT time since its also a ALTERNATE UNIVERSE. AFTER the three year training, GOHAN became 13, while GOSEN is now 16. (And Trunks would also be 16 right now).

As for the Androids. No one knows their real age but they are assumed to be young. They act more like hot-blooded teenagers, so I'm keeping them at 17 years old.

Hopefully that clears any confusion you guys might have experienced...I hope there was some confusion or else I thought of this and typed it for you guys for nothing.
