Let me get a few things straight, or as straight as I can remember...

Aren't Melanie and Max brother and sister? And wasn't their dad Trent?

So if Melanie is Carly's daughter, Carly had an affair on Lawrence with Trent?

Or, are Max and Melanie full brother and sister? Therefore Carly is not her mom, but Mia's?

We dont' really know a thing about Mia, so it is very much a possibility that Carly is wrong about who her daughter is and Viv might have stumbled onto the right girl.

Thoughts? Help?
