Thames Thursday - "Sapphire and Steel" Assignment 3

We continue our discussion of "Sapphire and Steel" with Assignment 3.
This is an odd episode (aren't they all?) on several levels.

In Assignment 3, Sapphire and Steel assist a family from the future left stranded on earth. Sapphire and Steel know where the family is. Their problem is getting into the family's invisible "pod" on the top of an apartment building. Watching our bright Steel walk along the edge of the apartment building with his heels hanging over is great suspense.

I don't want to over-elaborate about the subject because it interferes with the discussion. I will only mention a few observations:

1) "I Get So Emotional Baby" 
When the creepy doll Steel strangled turned into Sapphire, Steel was overwhelmed with grief.

2) "I'll Be Watching You"
Steel saw the cringe-worthy flirting and fawning between Silver and Sapphire and Silver.  Somehow, Steel kept his jealousy and his temper in check and didn't deck Silver.

3) "Vous le Vous"
As I realized with A5 and A6, there were several visual and verbal messages. In A3, Sapphire and Steel had what I call their "dance around the bed".

4) "Here's Looking at You, Kid" 
I've wondered if the scene where Steel gave Sapphire the infant wasn't a hidden message.  That opens the door for a whole myriad of questions.  Unfortunately, the way the series ended, we can't speculate an answer to that question.
Never mind teasing us with vague terms about the chickens,
and grass and weeds, or the eggs, fruit and milk.

5) "Born Free" - Sapphire and Steel were surprised that there were no animals in the world of the future.  The concept of having pets was foreign to the couple from the future.

6) "You May Be Right" - In A3, Silver showed up to provide assistance. Silver is designated as a "technician", and he informed Sapphire and Steel that he was incapable of making a mistake. Although he may have hidden it from Sapphire and Steel, Silver does make mistakes.

Despite the gross moments with the animals in the abattoir, A3 has some gorgeous scenes.

The rooftop scene, when Sapphire steadies Steel to keep him from falling, is one example.

So, A3 is open for discussion.  One question on my mind is whether Sapphire was playing with Silver to provoke Steel, or whether Silver was playing with Sapphire to irk Steel.
