Originally, unity was going to be depicted prosthetically as the one hand inside the other, but that was dropped from the script. The special effects team then came up with what we see, the very effective shot of the two people going into each other, so to speak, when they join. (edit)

Zhaan: Why did you lure us here?
Tahleen: Search yourself, Zhaan. You know why.
Zhaan: I do not. What I do know is you invaded my soul last night and you left me bitter. (edit) Crichton: (after being released from the illusion of Lorana) So now what, kill me, cage me, teach me tricks? (edit) Tuzak: I know who you are.
Zhaan: I know who you are. I do respect yout teachings Pa'u Tuzak.
Tuzak: I respect your choice of murder victims. (edit) Zhaan: Should I give Tahleen what she wants?
Tuzak: Oh, she would like that!
Zhaan: Will she use the ability I give her to hurt people?
Tuzak: Certainly. But she may also free your planet from tyranny. (edit) D'Argo: Something Crichton said is disturbing me.
Rygel: Finally! I've been saying that since he arrived.
D'Argo: It's what he said about us all having the same dream.
Rygel: It wasn't the same. Mine was better than yours. (edit)

We hear the shocking revelation as to why Zhaan was imprisoned: she murdered her lover, who was also one of the Delvian spiritual counselors. (edit) Delvia is now under the imposition of the Peacekeepers. The conservative Pa'us that refused to give up their control when the tenure was up brought the PKs in, and Delvia has never been the same since. The Peacekeepers refuse to give control up easily. (edit) This episode marks Zhaan's ascension from a ninth-level Pa'u, to a tenth-level one. She now has the power to protect others. (edit)

Crichton: That's my underwear.
Aeryn: What does this say?
Crichton: Calvin.
Aeryn: Well, then, they're not yours.

Crichton was wearing Calvin Klein boxers when he left Earth; Aeryn is looking at the tag in the back of the waistband, which carries the brand name. This is a reference to a scene in the 1985 movie Back To The Future. (edit) Title:

The title is taken from American composer George Gershwin's most famous composition. (edit)
