This is just a guess:
Your sons information could be saved on a different part of SOE's databases than yours. So if there were something to happen to your server, or if they were even just to take it down and run simple things on it.
I've seen similar issues happen in the past with couples I know who play.
Or it could be something else /shrug

"What do you want to be when you grow up?"
"I want to be a unicorn!"
"Awww, why's that?"........
"So I can stab people with my face."
