In addition, the producers of the show have apparently been looking into the idea of spicing things up in the relationship of the two characters, possibly by introducing a pregnancy to the story.
However, it seems like this idea is not quite on the table just yet, as there isn’t much point in doing it in the current state of things. From the sounds of it, the idea is definitely on the table for the future, but it wouldn’t work out right now.
Of course, there are also other things the producers of the show could do to make things more interesting for Castle and Beckett and they don’t have to immediately jump on the idea of a pregnancy. The situation with the two characters is dynamic enough that there are lots of options available.
Especially in the peculiar state of their relationship right now, a situation that leaves many options open and the writers really just have to pick something from the array of possibilities. We are as curious as most fans to see where this story will end up.
First the writers and show runners should respect the characters and the fans. This would require adherence to certain specific and unbreakable/Unbendable rules. My opinion of what these rules should be are as follows:
(1) Caskett have only been married for a year and they are very much in love 24/7 even though they cannot show it around others.
(2) There will be no unfaithfulness of any kind.
(3) There will be very little, if any, flirting and/or swooning as occurred with Danny and Eric.
(4) There will always be mutual respect and understanding.
(5) There will be no hurting comments during make believe or real arguments.
(6) Every day will end with no hard feelings but, instead, a reassurance of their love.
You see I have been married for over 50 years to my high school sweetheart and the above pretty much outlines what it takes from both parties to make it last beautifully. I might add that I hope that when Castle and Beckett start working together on the case that progress picks up rapidly so that the farce only lasts 2 or 3 episodes and that the fans are kept in the loop on the case and not in the dark as before. One final thing – feelings have been expressed by both parties regarding the “split” and they have made up and promised to make their marriage work. Now drop it and do not bring the “split” up again.
