No, I saw that part. That's what made me think it was fake. But at the end the doctor used the stethoscope to examine her. I'd imagine the doctor would be like "Um, there's no baby in there". I guess it was just "convenient" editing. But, it's not like Tara would tell the doctor that she was pregnant, so he wouldn't be looking for anything, just see a big bruise on her stomach. All the rigamarole in the hospital just threw me. Tara jumped through a lot of hoops to make this plan work.
Oh well, eventually Jax will find out that Tara was never pregnant. THAT will certainly be fun to watch.
