The power of saliva.
So I’m sitting here watching Sam’s “death”. And Gordon puts a bandanna around Dean’s mouth so he won’t yell and warn Sam.
Now lets step away from Supernatural and think of all the other Hollywood movies and TV shows where the victim is tied up and some kind of cloth is out around their mouth.
"Ok, where are you going with this?"
I’m leading to a survival tip. Very simple and basic. Most fabric stretches when wet. So killer or whatever has a piece of cloth over your mouth. Use your saliva to soak the cloth. Push the cloth away using your tongue as best you can. Yell out as soon as you get free.
This also works for duck tape, try to fold your lips in like you’re pretending to be an old person and try to force your tongue inbetween getting the tape moist, (haha love that word, makes people cringe.) It’ll release the stickiness letting you yell.
Last one, what if it’s their hand. This one might gross you out a bit but fuck that, you’re being silenced, you need to yell! Lick the persons hand. DO IT! They’ll possibly react and remove their hand. Yell before the hand comes back.
Real world shit for you. Now back to Supernatural.
