Daydreamin'
From "Terra"
This set comes after "Regrets". 
Cybersix and Data 7 are on "patrol".  I put the word in quotes, for she isn't in a patrolling mood right now.  This is one lady with serious regrets, and it's only episode 3.
What is she looking at?  Something in the street scene below.
Only Durer's "Melancholia", over 3 centures old, transmits the emotion of melancholy and sadness better than this frame.  (Disney had better be really worried.)
Now we see what she's really looking at.  The red dress. 
 
An excellent choice!  She's got the neck and shoulders to look smashing in it.  (Dressing like a man hasn't hurt her fashion sense at all.)  The pearl necklace ensures that eyes are drawn to one of her best assets without being distracting.  Add a pair of gold earrings and black shoes, and the lady's dressed to kill.
And not just Fixed Ideas.  (Now in real life, we have no idea if either of them can really dance, but I've been told that learning together is really fun too.)
 Now we see what she really has in mind...
Umm, yes.  Lucas is not going to have any problems obliging the lovely lady...
Alas, cruel reality intrudes.  At this moment, Terra has struck at the theatre down the street, Lucas is in trouble, and Cybersix is still in dreamland...
...that is, until the sirens in the distance and the sound of the fight yank her back into the real world.
ULP!!!
I'm so glad they didn't use the "anime sweatdrop", for this blush makes her embarassment seem so real, that it can't help but make me remember the times I've been caught daydreaming too. There's nobody on the roof but Data 7 that would notice, but she still blushes.  Bravo!.
Who hasn't been depressed, and daydreamed to excape the pain?  And who hasn't been caught daydreaming and come out a little bit embarrassed like Cybersix here?
In "Regrets" and this scene, I think the cartoon succeeds in working her even more into our hearts  by showing us that she too indulges in one of life's escape hatches, as well as succumbing to one of life's more embarassing moments.  In this way, we come away even more convinced that she is more human than she believes.
Although Cybersix in the comic often dresses like a woman, this sequence is the only time in the cartoon where Cybersix is shown wearing a dress.  Thus, it holds a special spot in the hearts and minds of Cybersix fans, and pops up in several places in Cybersix fanfiction and on the Cybersix message board. 
NOTE: Compare the hair between the last dream JPEG, and the second from the last.  Pretty much identical.  A nice anchor point to help the transition between dream and real worlds.
