i am a member of www.cwtv.com

and i got this email that said this along other things... but anyway it said:

Ready for some juicy spoilers? OK, but this is just between us. When new episodes of One Tree Hill return on Monday, April 14 at 9/8c... we'll find out that Lucas and Nathan are very closely related.

really?
1. i don't get it, they are already closley related.
2. does anyone know what this means.
3. is it true?
4. why havn't we heard anything about it already?

please comment on what you think.
i'm rather confused.
