Heroes in a nut shell:
Everything I do is to protect you! Let me be myself! Why don't you tell the world who you are? If we tell the world who we are, we die. Are you my friend or are you my enemy? <new hero for three episodes dies> We must protect our kind. We must destroy their kind! We must protect their kind! <original hero dies because contract negotiations fall through> I'm doing this for my son! Think of the scientific benefits! We have to go back in there and rescue them. We trust them and we die. <original hero dies until cut scene when they aren't really dead> We can't live without trusting them. Nemesis!
That's pretty much how its been for years worth of seasons now. Its the same shit compiled over and over again. Everyone still has the same role, the same mindset that everyone has had since the beginning. My gf and I made a drinking game out of Claire crying in episodes. Got drunk almost every time we sat down to watch it.
