Headscratchers / Kiss Kiss Bang Bang

• Why didn't Harry and Harmony just call Perry to warn him, rather than running all over Macarthur Park having a shootout?
  • The answer is probably that Rule of Cool trumps logic, and that it was an easy way to get Harry to witness the girl in the pink wig being shot.
  • It could be that having to answer his phone would draw more attention to Perry; Harmony may have been planning to draw him away from the park.
  • Perry could have turned his phone off. It makes sense to do so when you're tailing someone.
  • Harmony is a bit of an air head, and poor Harry was high on Demerol, and delirious with pain.
  • Also, did Harmony even have her cellphone on her? She was working a Christmas party as a hostess, and she probably didn't have any pockets on the dress she was wearing (and when we see her talking to Harry on the phone after his visit to the hospital, it could have been during her break back when she could have gone to get her cellphone from any bag she had and had to place it back when she had to get back to work). At least we know Harry had an excuse: was stoned from the medication, so he probably wouldn't have thought of it either.
