So by saying the clutch is done do you mean I need a new clutch?
And I am unsure if the slave was original or not the one I took off looked like it had been there for quite some time but the piston I believe is what it's called was stuck in place all the way back and not moving at all.
I was thinking the linkage could be something that was rigged and never worked properly I can get back under there and take a video of what is going on, I'll just have to wait till my fiance gets off work so he can be pushing on the pedal he will be home in a couple of hours. But in the mean time I'll post a picture of the linkage.

Yes, in a slave cylinder system the clutch will work untill the disc wears down to nothing, like brake pads, then the pressure plate spring loaded section moves closer to the flywheel, pressing on the worn thinner disc, The slave cylinder pushrod cannot move the pressure plate far enough to disengage the clutch, because the disc is worn too far. it looks to me like your clutch fork isnt moving enough to disengage the clutch, which is why the driver had to "hard shift " it without a clutch to move it.
