Prototype 2/Fridge

Fridge Brilliance

 * Heller's characterization throughout the zones is an exact mirror to Alex's. In the Green Zone, he mostly cared about protecting the citizens of NY, like Alex in the end of the game. In the Yellow, he was mainly seeking revenge, and in the Red Zone, he only cared about saving a family member...
 * At first, you may think its pretty stupid of Black Watch and the Marines to just ignore a guy gliding down and landing right beside them in earth-shaken crater. Its obviously Heller or Mercer up to more shenanigans at their expense. But then the Orion project and "Evolved" are introduced and it makes sense. They expect superhumans among their rank popping in and out. Its why just standing there like you belong there after pulling a blatantly mutation-enabled stunt shrugs off suspicion instead of giving them more time to suspect you. They think you belong there.

Fridge Horror

 * Combined with Fridge Brilliance until the horror kicked in - Note what happens when you consume a Civilian or Marine. Heller just absorbs them pretty much instantly. No need to "Prepare" them like Infected or Blackwatch. Heller is actually giving the innocent a quick death if he really has to consume them. This really abstract moment of "Heartwarming" is then upset with the realization that Mercer was killing innocent Civilians in horrible, painful ways not out of necessity to make them edible, but completely and utterly out of choice. Retroactive warning signs, anyone?
