Script Excerpt:

DELENN: And the picture always ends with your head imploding.

SHERIDAN: I want you to know I deeply resent that.

DELENN: As Ivanova says...tough

By now she's right up to him.  She's utterly impervious to his
comment, and he knows it.  They kiss, briefly.

SHERIDAN: You haven't known me this long...to know me this well.

DELENN: We're old souls.  Deal with it.

SHERIDAN: We're halfway to Z'ha'dum.  They'll expect us upstairs in a few
minutes.

DELENN: One can accomplish a great deal in just a few minutes.

And she smiles.

Sheridan nods, not buying it.  Delenn notices his hair is mussed in back,
discretely smooths it.  They've been busy.
