The nephilim baby story heats up with the return of Cas, Dagon and Kelly. This is a Cas-centric episode, so we may not see much of the boys. Cas is taking on Dagon and touching Kelly's baby bump. Kelly seems to have escaped Dagon so good for her. The angels are involved in a big way with Joshua making a reappearance. Finally, welcome Amanda Tapping! Another Supernatural alum comes back to direct!
ETA: We see Cas's return and we are told officially that the baby will be born around May 18 :) AND we get a quick handwave as to why this won't be a nine month pregnancy. What do you think about what we know about this episode? Tell us in the comments or in the discussion thread for episode 19.
