At this point it's not a matter of if, but when Blade will lose his leg.
Also for people wondering why he won't stop drinking when his leg is that bad, he literally can't.
Take it from a former drunk. When you are sweating, vision blurry, cant hold your hand straight enough to light a cigarette, watching the seconds tick on the wall while debating just putting a noose around your neck when trying to quit a majority of people say fuck it and just go back to drinking.
Also, if he stopped on his own I would give him four days, tops. Blade would have to be in a detox center and not a shitty one. Around the clock care, heavy medical dedication with constant supervision to make sure the detox didn't kill him.
