You are right Capri Kay was asleep
My take, Perfect! for the "drapes opener" who Ref: lucab19 "must have had ninja-like stealth skills" - sounds like.... Fredo! to me

Michael surviving the Tahoe shooting screws up all Fredo's arrangements!
oh! Fredo, It was all lies -- uh -- everything! among others -

  • Never met Ola

    Fredo: Two million dollars in the seat next to me in the plane
    What the hell is goin' on anyway? I'm totally in the dark
  • Fredo knew what the hell is going on! Fredo was not totally in the dark
  • Fredo knew Michael and Roth were in, on a big deal together
  • I doubt Fredo knew anything about the actual negotiations that Michael was being 'tough on' but....
  • even if Fredo knew, why would Fredo think it'd be good for the family? for Roth to get any inside help
  • Why Fredo needed to be bribed with “something in it for me” reward? for it'd be good for the family
  • and what was Fredo's little help? to get his reward

Michael: You believed that story You believed that - We don't! either

So how can we believe Fredo, when Fredo says -
