I'll leave this be. You're only digging your own hole deeper.
Why? Because its plausable to have his knee fixed off screen?
I mean, how much happened off screen that you wanted to be on screen and explained just like 'how did he get back into gotham'?
Whats to say he didnt have surgery on his knee? Whats to say he didnt just tank painkillers for a while either? Nothing. Nothing says he doesnt, nothing says he does.
Its clear that your one of those dunces who need everything explained on screen. You need everything explained to you so you dont have to use that limited intellect you possess.
But oh well. All I get is 'you dig a hole deeper' or a comparison to al qaeda. Not one actual relevant argument in which you can back up any of your points.
The Nam syndrome; full of utter sheite.
