Sorry, no. If you don't have access to the email address I can't help. Try putting that email address in the "Email or Username" field, as you could have gotten the username slightly wrong (it seems like you have it right but you never know).
Otherwise, if he doesn't remember the password he'll just have to wait until he gets back home.
And for others: I checked both accounts and the story checks out, so stop throwing round wild accusations without any evidence. Thanks.
