It felt like 9/11 or something to me.
I was thinking "How did he not pick a decent track"
but then I realized he picked his first.
That death was kind of stupid, but probably the best way to cut him off really fast. I imagine they had some sort of deadline and they needed him to die in some way, and having him randomly fight a boss would be too dynamic to get him killed. Although..
they could've been fighting a boss, shortly after kp gets blown away by a knockback hoe to over a hill
they look down, he's lying in a bed but it looks like he's just lying on grass or something
they go down
he's like
"cough cough GO ON HEROES, THEY ARE GET AWAY"
Although I suppose we need to know the next plot points to formulate a better death.
