Let the two glittering stones
one is red one is blue
connect the past.
Two friends sharing power
open a window to
a new world that glows
The next world waits for you.
In a house in Lilycove is an old man that talks about his past, and a locked door.
In a house on Seven Island is an old woman that talks about her past, and a blocked door.
Why do I get the feeling they are connected? Two houses with locked doors and old people that say almost the exact same thing, and Braille that talks about a secret new world. Everywhere else online that I've looked, they think that it just means trading and battling, but you know about that even before you read the Braille. I mean, that's the reason you go looking for the Sapphire, so you can trade between LG/FR and R/S/E. I wonder if someone would test this theory, and post their findings.
Link up LG/FR with R/S/E, and go to the houses. Talk to the old people, and see if anything happens.
