Hilarious in Hindsight: It’s a darker style of humour, but there is something amusing in how Tony suggests that one reason Earth should hold on to the tesseract is that another party may be planning to use all six ‘metashapes’ to create some kind of ultimate weapon.
Nightmare Fuel: The whole concept of the Winter Soldier becomes even darker here, as not only does Steve have to deal with the knowledge that his best friend was brainwashed and turned into an assassin against his will, but also that he killed Bucky with his bare hands.
