Episode Summary from en.wikipedia.org:
Skye is now integrated into Coulson's team as a consultant. Their next assignment is in Peru, tracking a "0-8-4", a S.H.I.E.L.D. prefix for "an object of unknown origin". Once there, the team quickly realizes that the object is actually a piece of forgotten HYDRA technology powered by Tesseract energy. Coulson meets with a former ally, Camilla Reyes (Leonor Varela) and brings her onboard the team plane. Later, Reyes betrays Coulson and plans to take the HYDRA weapon for herself so she can take over Peru. The squabbling team members band together, utilizing each of their talents, and save the day. Skye receives a text message from another member of the Rising Tide and confirms her allegiance to them. Afterwards, Nick Fury (Samuel L. Jackson) scolds Coulson for the damage to the plane.
