Little things you didn't think of until way later.
 

You know those little details that may mean much but didn't click for you until way later? Things that were always there but you didn't get that they were important, care to share any of them?

For me, I recently realised Oob in Dragon Ball had a significant haircut. When I first read the Super chapter where it is revealed he inherited Kaioshin power, I thought it was a retcon that was never intended back in the day. But then I realised something, all the Kaioshin had mohawks, just like Oob. So maybe this was an idea even back then?

I always thought it was more like it was a human version of Buu's antenna thing.

When I'm at a job interview, I'm asked questions that I don't know how to answer when asked, but then when it's over and I've left, a better answer comes to mind. By then, it's too late.
