Attention fans of 'The OC'... I need 2 know r Marissa and Ryan half siblingz =0?

Question

Ok soo it sounds pretty crazy I know.. but i wanna confirm this. I havent watched all the episodes of The OC, but i read online that Frank Atwood(Ryanz dad) and Julie Cooper(Marissa's mom) have a baby... is this true? and if it is then wouldnt that make Ryan and Marissa(if she was still alive) half siblingz??Please someone confirm !! Thnx in advance =)

This is where I read it on wikipedia:

http://en.wikipedia.org/wiki/List_of_recurring_characters_in_The_O.C.#Frank_Atwood

The thing is frank atwood section:

"When Julie tells Frank that she's pregnant with his child, he panics and leaves. When he has dealt with the news and decides that he does want to be involved, he finds Julie having dinner with Bullit, who still wants to marry her. He tries to stop Julie and Bullit's wedding by running to the church. However, when he gets there the church is empty because Kirsten Cohen gave birth in Berkeley and couldn't attend the wedding, so Julie moved it to Berkeley. When Julie and Bullit are at the altar he calls Kaitlin, who puts him on speaker phone. Frank tells Julie that he wants to be with her. Julie decides to remain single and go to college. At Julie's graduation he attends with his and Julie's son, Kaitlin and Bullit"

Seems to me that theyre related.. which would be scary ... but im probably wrong..

Answer 1

I dont know if they have a baby, I dont think so, but Ryan and Marissa are not related. At all. Completely not. Ryan dated Seths "aunt" Lindsay and Seth had tried to ask her out before he knew they were related but it didnt go well.

Answer 2

No, Ryan and Marissa are not related.

Frank and Julie only get together in the last (4th) season - after Marissa is dead. And Julie's child is only shown in glimpses of the future seen in the show's very last episode.
