Die Hard 6 if it gets the greenlight if he were to team up with his daughter Lucy then where does that leave Jack? But for Holly she should definitely return to the franchise though, McClane's ex-wife there would obviously still be some love there
I was incredibly bored one day and wrote a treatment where Lucy gets the whole family together for Christmas dinner because she has big news for them. They go to this big restaurant atop of a 5-star hotel where some big political thing is also taking place. So we start with family dinner (Holly, Matt, Jack, Lucy and John) until **** goes down. Y'know, wrong place, wrong time, McClane style.
Here's some dialog bits for *****s and giggles:
JOHN is at the RECEPTIONIST’s DESK. He’s UPSET.
JOHN: Well, check again!
HOLLY, JACK, LUCY and MATT walk up to him.
RECEPTIONIST: I’m telling you, there’s nothing under-
HOLLY: Reservation’s under “Gennero”.
JOHN (to Holly): Why Gennero?
RECEPTIONIST: Ah, here it is. Table six. Follow me.
They do.
JOHN: There’s three McClanes here, only one Gennero.
MATT (to Lucy): And me.
LUCY (to John): And Matt.
JOHN (to Holly): And the kid.
MATT: Older than your son, actually.
Jack GLANCES at Matt.
MATT: B-but shorter. Weaker, too.
McCLANE: Gennero-Farrell? Is this a joke?
LUCY: I already changed it to Gennero years ago, I can’t change it back to McClane, Dad.
McCLANE: But Farrell? (to Matt) No offense.
MATT: Taken.
LUCY: I knew you’d make a fuss.
McCLANE: My own daughter doesn’t want my name...
HOLLY: John...
McCLANE (to Jack): You’re still McClane, right?
JACK: Off-duty, sure.
McCLANE: See?
A beat.
McCLANE: Off-duty?
JACK: The Agency assigns us fake IDs for field operations.
McCLANE: What’s your “field operations” name?
JACK: It doesn’t really matter.
McCLANE: No, come on, we all wanna know.
MATT: I don’t.
HOLLY: Let it go, John. Enough.
JACK: It’s Johnson.
McCLANE: You’re an agent Johnson? Goddammit, Jack.
And the last scene:
JACK and MATT are taking a badly injured JOHN to an ambulance. HOLLY and LUCY walk next to them.
LUCY: Uh, night’s kinda ruined now, but... I had something to tell you.
JOHN: Can it wait until tomorrow, honey?
LUCY: Mom, dad... I’m pregnant.
JOHN and JACK GLANCE at Matt.
MATT: Did I bang my head? ‘Cause I’m seeing double...
HOLLY hugs Lucy TIGHT.
HOLLY: Congratulations, honey!
JOHN leans on Matt.
MATT: Hey, hey, John, buddy... look, uh, let’s take a moment here, huh?
John PATS Matt on the shoulder. He half-smiles. Also could be wincing in pain.
JOHN: At least someone will play with those dolls of yours.
MATT: They’re COLLECTIBLE ACTION FIGURES and so NOT for playing-
John limps his way to LUCY and hugs her. Jack puts his hand on his sister’s shoulder, smiling.
JOHN (to Lucy’s ear): Him?
JACK: Uncle Jack, huh?
Lucy LAUGHS. She jokingly slaps John.
LUCY: Dad...
JOHN: I’m proud of ya, kiddo.
John sits on the back of the ambulance. Two paramedics walk up to him. They’re all standing around John as the camera PULLS AWAY.
JOHN: Can I get my morphine now?
Also, John has two cats in his apartment: Hans and Simon.
I know, I know. Fan fiction, huh? I'll shut up now.
