messages.content: In this script, at a nightclub for Ruth’s birthday, Dave’s old uni friends, Lauren (29) and Kelly (29) indiscreetly tell his younger sister Ruth (19) whom they’ve just met tonight, all 3 very tipsy and barefoot, about the time when, back in uni days, after Dave had been a volunteer in a stage-hypnotist’s show, the hypnotist told them their friend Dave was incredibly hypnotizable. He gave Dave a post-hypnotic trigger for the girls to use to put him under themselves (“Dave the slave” and a finger-snap: which they made frequent use of subsequently, but he doesn’t consciously remember ever being under - any of it!). Ruth is fascinated, excited to think of her big brother under their total control, literally at their feet like a servant! They call Dave over, and Lauren drops him there & then!

messages.content: **Title: Ruth's Birthday Surprise**
  
  INT. NIGHTCLUB - NIGHT
  
  The club is alive with pulsating music and vibrant lights. RUTH (19), a young woman with a bright smile, is surrounded by her friends, celebrating her birthday. Among the crowd are LAUREN (29) and KELLY (29), Dave's old university friends, who have just arrived.
  
  RUTH
  (to her friends)
  I can't believe I'm finally 19!
  
  LAUREN
  (grinning)
  Well, we've got a surprise for you, Ruth.
  
  KELLY
  (nods)
  A night you'll never forget.
  
  The three of them laugh and clink their glasses together.
  
  CUT TO:
  
  INT. NIGHTCLUB - LATER
  
  The trio is now sitting at a table, drinks in hand. They're all tipsy, and LAUREN and KELLY are barefoot.
  
  LAUREN
  (leaning in)
  You know, back in uni, Dave was a volunteer in a stage hypnotist's show.
  
  KELLY
  (excitedly)
  And the hypnotist told us that Dave was incredibly hypnotizable!
  
  RUTH
  (intrigued)
  Really?
  
  LAUREN
  (nods)
  Yeah, he gave Dave a post-hypnotic trigger for us to use.
  
  KELLY
  (whispering)
  "Dave the slave" and a finger-snap.
  
  RUTH
  (wide-eyed)
  Wow, that's wild!
  
  LAUREN
  (grinning)
  We made frequent use of it, but he doesn't consciously remember ever being under.
  
  RUTH
  (excited)
  I can't believe my big brother was under their total control!
  
  KELLY
  (laughing)
  Literally at our feet like a servant!
  
  RUTH
  (determined)
  I have to see this for myself.
  
  RUTH gets up and walks over to DAVE (22), who is chatting with some other friends.
  
  RUTH
  (to Dave)
  Hey, big bro! Come over here.
  
  Dave looks at Ruth, then at Lauren and Kelly, who are signaling him to come over.
  
  DAVE
  (confused)
  What's up?
  
  LAUREN
  (smiling)
  Just come over here, Dave.
  
  Dave hesitates for a moment, then walks over to Ruth's table.
  
  RUTH
  (to Dave)
  Lauren and Kelly have something to show you.
  
  Dave looks at them, still confused.
  
  KELLY
  (whispering to Lauren)
  Now!
  
  Lauren snaps her fingers, and Dave suddenly slumps in his chair, his eyes glazed over.
  
  RUTH
  (excited)
  Oh my god, it worked!
  
  Dave is now completely under their control, and Ruth can't help but laugh at the absurdity of the situation.
  
  FADE OUT.
