So it frustrates me (in whump movie scenes) when you can tell the actor has never been in this kind of pain before (or at least they're not translating it to the scene!)
Caning. Whumper should yelp and flinch, then groan and cover the spot protectively afterward.
Whipping, whumpee should should SCREAM. Do a lot of shrieking and then shudder and whimper and huddle into yourself.
Also the pain BUILDS. Even if they don't strike the same spot (they probably will though).
If whumpee is trying to be stoic, what are they doing to hold in their screams? Gripping a chair leg? Holding their breath? Cursing? At every blow, they're still going to wince, flinch, clench their fingers and toes, hyperventilate, and every other reflex your body does to get you away from danger. and if they have to hold a position they WILL be shaking by the end.
Gun pointed at they're head? Flinch. Look away for a second. Something to show that they're scared of dying or AT LEAST scared of the pain on the way.
Got cut? That pain often comes in waves (especially with infection!) so they'll be talking, then they'll wince and grab the spot with a grunt of pain, then like, "shhit." or something. Grab another shot of whiskey.
And sudden traumatic injuries they've never had before, yes, they can walk it off for a minute, if the limb is mostly functional. But as soon as that adrenaline fades and they feel like it's safe, they are going to drop, screaming.
Tied up. The instinctive reaction is a quick tug at the bonds and then start panicking at having their arms trapped.
On that note: with their ankles and wrists tied behind them, you may still be able to roll just as fast as crawling!
Also a note for whumpers, if you're threatening whumpee with a stiletto:
You are threatening to STAB into the SIDE of their neck, not slice their throat across the front!! You also want to keep them very close to you (manhandle them!) so they can't worm out of your grasp while you're threatening them. Think like a hug. <3
