He's 800 years old, he isn't defending himself much physically.
I'm not suggesting that he would overpower the guy or win
But am I seeing things wrong, or is he holding a glass in his hand? That alone is freaking weird
Also I can't tell if they're handcuffed together or some bizarre excrement
(if you said this was some senile guy with dementia or something like that, then everything about this makes much more sense, though he was arrested for a DUI like 2 months before? So the most sense would be hearing that he was just a excrement faced alcoholic and probably was annoying the intruder unless he had his drink)
