San Juan

San Juan is the capital and most populous municipality in the Commonwealth of Puerto Rico, an unincorporated territory of the United States.

Getting to the City
Phil Coulson decided to separate his senior S.H.I.E.L.D. agents into two groups, one to protect Raina in Vancouver, the other to accompany him to San Juan to destroy the city that matched the City Blueprints before HYDRA use it, in combination with the Diviner to create a Weapon of Mass Destruction. His team consisting of Bobbi Morse, Leo Fitz, Jemma Simmons, and Alphonso Mackenzie take a Quinjet to get there.

Morse and Coulson make sure that they are not tailed, leaving the others on the plane. Morse has a contact named Diego who planned to meet them at a plaza, but he runs late. While awaiting him, Morse questioned Coulson's leadership style, comparing his to Nick Fury's; she told him that Fury would plan for "acceptable losses" in this mission. Coulson responded that not only does he hate that term but that it will be zero. Morse and Diego then meet.

Meanwhile, Mack grew tired of the awkward silence between the two scientists and decided to look at the plane's landing gear to leave them alone to talk. While Simmons, tearfully, tries to speak about her reasons for leaving him without her for so many months, Fitz interrupted her to explain that he would rather work for her than with her, making her leader of the science team.

Coulson and Morse are given hand drawn blueprints to Castillo San Cristóbal, a garrison older than San Juan. Diego decided that he would not accompany them because of the legend that the place is haunted and those who enter do not return.
