Gaben will then slowly drop his head and whisper into the microphone with a wry chuckle - "You fool. You have just activated my trap card."
Immediately, the Half Life 3 release will drop. Gaben has been holding it back, continuously updating for decades, awaiting exactly this moment. The judge, completely flabbergasted at the proceedings will immediately declare a mistrial. Legal scholars will then study the "Gaben defense" for decades.
Forget HL3; where's HL2: Episode 3? I wanna know what the fuck happened to that garden gnome I carried all the way from the beginning to the rocket at the end.
If this happened I think Gabe would just say "it's not happening, not at least the way you all want" and then we get some half life cyberchip augmented reality game in another 15 years (it is good though)
