Glad to know Nick (spoilers)...
Glad to know Nick is following in his mother' footsteps in getting people killed. He knocks Jake into a ditch where a zombie bites him on the arm, and rather than putting him out of his misery, he cuts his arm off, fails to make a good tourniquet, and lets Jake to bleed to death. Why? So he could save the guy who is clearly too far gone to come back, who puts the entire ranch, including his own sister's life, in jeopardy. You got to love the rational decisions this guy can make.
I'm sorry if this post annoys people who enjoy the show, but after seeing that last night, I'm literally questioning how the writing got this bad.
