[An artificial heart appears in Q's hand. Picard reacts, looks at it, looks down at his burned chest, and gets a look of recognition on his face.] Picard: "Is that..." EDIT Q: "Your artificial heart, you might have lived if you had a real one. Instead of this unreliable piece of technology. [he tosses the heart to Picard. Picard studies it]. By the way, how did you lose yours anyway?"
Q: "Really?!" [Q gestures with his hand to a scene of a young Starfleet officer fighting hand-to-hand with two Naussicans, easily holding his own. Once he has two of them fairly subdued a third one comes up and impales the young SF officer through the back with a large knife. The officer drops to his knees, looks at the knife in his chest and laughs briefly before dropping to the floor on his side, seemingly dead.]
Q: Did I hear a laugh? It's so unlike you, Jean-Luc, to have a sense of humor; especially about getting stabbed through the back.
PICARD: I was a different person in those days. Arrogant, undisciplined, with far too much ego and too little wisdom. I was more like you.
PICARD: The pity is that I had to be impaled through the back before I learned that lesson. I started that fight with those Nausicaans. I started it because; because I was young and cocky. If I'd been more responsible in those days I wouldn't have needed this heart, and I wouldn't have died from a random energy surge 30 years later.
[Starbase - Picard's quarters] (Picard, in old style uniform, gets slapped across the face by a woman who then storms out of the room) MARTA: Bravo! Bravo!
COREY: (a red-haired young man) Yes. Boy, she must've hit you pretty hard. Of course, you deserved it.
