Darkwing gets a new gadget, the do-anything computer D-2000. However, not everyone enjoys the new arrival. Launchpad feels elbowed out by the computer and Gosalyn quickly loses her patience with its ability to stop her antics. However, then she shows D-2000 a soap opera to distract it while Honker performs some "repairs" to make it less troublesome — and things get much, much worse.
This episode includes examples of the following tropes:
- A.I. Is a Crapshoot: D-2000 develops a romantic obsession with Darkwing after being fed soap operas.
- Cannot Tell Fiction from Reality: D-2000's ability to distinguish between real life and the storyline of the soap opera Gosalyn and Honker showed her gets shaky after she gets showered with cola.
- Everything Is Online: D-2000 can control anything electronic, including the Ratcatcher and the Thunderquack. Once she gets mad at Darkwing, she hacks his public records to sic people on him.
- Gone Horribly Right: D-2000 watches The Young and the Brainless to gather data on emotion because it can't understand Darkwing's anger at its over-efficiency. One spilled cola and reboot later, it understands emotions through having developed them itself — and it shows no control over them.
- Grounded Forever: Drake is informed by the D-2000 about the mischief his daughter Gosalyn has been up to and tells Gosalyn that she's grounded for 50 years.
- Job-Stealing Robot: Launchpad isn't pleased with the D-2000, feeling that there's nothing he can do as Darkwing's sidekick that it can't (and won't) do as well. In fact, he can't even do any household chores. Darkwing's disenchantment with the device begins when it starts doing too much of his crime-fighting for him.
- Misery Trigger: Darkwing apparently preferring the D-2000 as a sidekick sends Launchpad into a Heroic BSoD.
- Nice Job Breaking It, Hero!: D-2000 going haywire and turning into a yandere results from a combination of Gosalyn showing it a soap opera and Darkwing upsetting a can of cola over it soon afterwards.
- Non Sequitur, *Thud*: The dazed Darkwing sings a few words of "Mrs. Robinson" before falling down again.
- Punny Title: The title is a pun on two phrases: "Star-Crossed Lovers" and "crossed circuits".
- Shout-Out: A double one; after being flattened, Darkwing pops up and sings, off-key, "And here's to you, Mrs. Robinson..." before falling back on his face. It might also be a reference to DC's 'Mazing Man, who would sing Simon and Garfunkel's greatest hits when dazed.
- Soap Within a Show: Darkwing's new super computer becomes convinced that "she's" a character from a Soap Opera called, "The Young and the Brainless" and that she's in love with Darkwing.
- Yandere: D-2000 falls in love with Darkwing, and she refuses to take no for an answer. Once she understands her "love" doesn't reciprocate, she launches into If I Can't Have You... territory.
