Brothers & Sisters Season Finale

Jumping the shark didn't occur to me until you said it... although now that you mention it, "R"yan suddenly coming into the storyline, while "R"ebecca moves from previously unknown sister whom everyone is finally accepting to Justin's girlfriend?? It's pretty wild. Although I'm truly delighted that Rebecca and Justin got together, it's got to lead to some strange feelings for other family members. Thinking in terms of the family and what would happen if these were real people, well I'm sure Maury Povich would come calling if he could if these people really existed! It was bizarre enough for them to learn about Rebecca in the first place, in terms of a formerly unknown sister. Now for them to learn that she is not a sibling but this Ryan guy is... it will either freak them out or they'll be so numbed by all of the other stuff that has come out about their father that they'll just take it in. I wonder who will place Ryan?
