Pistols at dawn!

How’s your memory now-- getting any better?
If a sidekick of the main detective finds a body or bomb-making equipment or disturbing obsession artwork or some such unusual thing, they never say, “Hey I found a body or bomb-making equipment or disturbing obsession artwork or some such unusual thing.” Instead they go over to the main detective and say, “Boss/Guv’nor/Sir you need to see this.” or “There’s something you need to see.” And then they and the camera move over to whatever it is that the sidekick found.
This always takes me out of the story. If you find something, just friggin’ say so. I bet real life sidekicks are completely capable of verbalizing their discoveries without unnecessarily putting their bosses into a momentary state of suspense.
I had a book by a woman living with back-country indians in Mexico 70-80 years ago, in which she discusses the experience of living with people who don’t have much furniture – or anything else much.
There are always people standing behind you, waiting for their turn. Important people go first. Sometimes you dip and turn and give something to your kid standing behind you.
Is it to to keep the viewer in suspense about the discovery? If so …
I love the scenes where there’s a predictable conversation, and director/producer have some loud foreground noise, or otherwise makes the conversation inaudible, to make the viewer concentrate on the actors faces rather than their words. E.g. I remember Better Call Saul season 1, when Howard tells Jimmy they won’t employ him as lawyer, there’s a loud operating copier in the foreground.
They could do it like:
"Boss, there's a <loud revving engine>, it looks like <whooshing from pump>. Better come and look."
Star Trek TNG used to do this a lot as well to push the plot.
“Engineering to bridge.”
“What is it LaForge?”
“Captain, you gotta come down here and see this.”
I’d like the sidekick to say “You need to see this” and have it turn out to be a really nice sunset and all the detectives and suspects and bystanders and even the ME all stop what they are doing and admire the sunset for about 10 minutes commenting wistfully on the colors. And then they slowly wander back to the investigation.
Or if we’re sinking to “Naked Gun”-levels of humor, a scantily dressed female sunbather who doesn’t know she’s visible to the investigators.
You can work hard for years to get your Doctor of Physical Therapy degree but apparently all they teach you is to yell at someone while they struggle to walk using the parallel bars.
Or call them. “Let’s meet.” But JAFO ends up dead before the meeting.
Yes I know. Probably the 5th or 6th time that’s been mentioned in this thread.
But it’s still (over)used so often.
I’d field that phone call with “NO, I’m not driving downtown just to find you dead. Tell you what: give me the details NOW, then go hide.”
Which reminds me of a common trope (probably already mentioned here, possibly even by me) in which a main character becomes paralyzed from the waist down in an accident, and manages to get feeling back in their legs and eventually walk again through sheer hard work and force of will (with the help of their physical therapist yelling at them to “try harder!”).
It’s the worst sort of ‘happy ending’ glurge because it carries a subtle implication that anybody in the real world who becomes paralyzed and wasn’t ever able to walk again just didn’t want it badly enough.
This trope used to be extremely common, especially in old TV shows, but I don’t think it’s as common anymore, so it may be a better fit in " Dead or nearly dead tropes?".
Which reminds me of one of the tropes I dislike intensely.
My wife’s late husband and my late wife both passed away from brain tumors. They were not coherent, loving, and full of wisdom right up until they closed their eyes for the last time. It was the opposite.
Ah, dying of Ali McGraw’s Disease. However, even back then (the 70’s), there were films like Turkish Delight (1973) an early Verhoeven film (before he started believing his own press clippings) that has a rather “bracing” take on the realities of terminal illness (including a character with a brain tumor).
“I’ve had worse.”
In the immediate aftermath of the stroke I had 1. My right arm and hand were only good for hanging down from my shoulder and B. My right foot pointed down and the leg wasn’t much good for walking or standing. At no time did my leading PT yell at me. One time, though, a PT student was holding a 8" cone for me to reach for with my right hand. Each time he moved where I had to reach for it. After a while I said “You’re just fucking with me now, right?”. He was speechless and my Lead PT did a spit take with the coffee she had been sipping on.
They have to work their way up to 360 joules.
If you weren’t walking the parallel bars is it even PT?
This was in between the two bars. I had to relearn how to walk sideways also.
