When he arrives home, Stark announces that he is closing the weapons division of Stark Industries. He then spends his time downstairs building a new armored suit and a new arc reactor more powerful than the last one. Stark tells his secretary, Pepper Potts (Paltrow), to destroy the old arc reactor, but she instead puts it in a glass box. On the first test of his second armor, Stark goes up into the atmosphere and the suit freezes up. He rebuilds it to work in cold conditions and paints it red.
