Okay so I missed this one

Some how I missed this the "spoiler" for Season 4

The whole Teyla thing-(and I still wonder where it got
started! Anyone know? And any "fact" based behind it?)

Well this fan made this "quote" on JM's blog

"Lorr54 said...
I have a theory about Teyla’s baby. I thought I saw a glimpse of attraction on Rodney’s part for Teyla at the end of Irresistible. Anyhow, in Tao of Rodney, he thinks he’s going to shuffle off very soon and wants to leave part of himself behind, so (insert magic wiggling of fingers here) he made Teyla pregnant. Please! Think Immaculate Conception! Nothing lascivious involved! He just wanted his very superior DNA to live on.Well, because Rodney becomes a daddy while in his highly evolved state, the baby, being all innocent and pure and without baggage, will ascend at birth!Am I close?"

Come on! Seriously! I believe that when I read it. Hahahahaha.
