Loki just stood there in the lobby of the Avengers building he didn't know what he should do he planned his revenge and broke out of prison with his scepter while Thor was visiting the avengers. Loki now knew that all the avengers now lived under the same roof of Starks huge building. Hawk eye and black widow lived on the top floor, hawk liking the height and widow liking the view over the city. Bruce and Steve shared the next floor, Bruce's lab was just a few floors down. Tony and pepper had the next floor, well pepper picked out everything for the other floors and tony picked out everything for their floor. Thor had the floor right above the lab so when he came he could go to his floor without making much noise. And right above Natasha and Clint was the shared avengers floor, a big conference room. At that moment Loki knew how he would attack.
