Seifer and Squall are brothers

[Serapy]

I've already had provided evidence. The points in my first post actually happened in the game. The only difference is that I connected these dots (hints).

This...

There's no hardcore evidence that the game explictly states "Seifer and Squall are brothers". The same goes for the opposite. You won't find it,
either.

contradicts this.

There's a difference between evidence and "hardcore" evidence.

The points I listed in my first post have actually had happened in the game. These are evidence (Squall's scar is evidence, etc.) I connect all these dots to draw a conclusion that Squall and Seifer are brothers.

But there's no hardcore evidence that supports the whole thing, because the game never stated "Seifer and Squall are brothers." in a dialogue or something. The same goes for the opposite. The term hardcore is used for emphasis. Hardcore evidence... is something that's a lot more powerful than a hint (hint such as image, non-dialogue or whatever) So, I'm not contradicting anything...
