Ep 2. 0-8-4

The episode "0-8-4" starts with the team being sent to investigate a mysterious object in Peru that Coulson classified as an 0-8-4, an object of unknown origin. As the team heads to the plane, they find out that they have been joined by Agent Melinda May, who has been placed on the team by Coulson as his "muscle."

Upon arriving in Peru, they quickly discover that the 0-8-4 is a piece of Chitauri technology, left over from the alien invasion in The Avengers. As they investigate the object, they are attacked by a group of rebels led by Camilla Reyes, an old flame of Coulson, who wants to get her hands on the 0-8-4.

As Coulson and Reyes reunite and clash over the object, it is revealed that the 0-8-4 is actually a weapon of mass destruction that could destroy an entire city. Coulson and the team must race against time to defuse the weapon before Reyes can use it.

Meanwhile, tensions arise between the team as they struggle to trust each other and find their place within the group. Skye, still not an official agent, rebels against the team's methods and seeks Claire's help to hack into S.H.I.E.L.D. files. Fitz and Simmons, the team's resident scientists, are at odds over the best way to handle the 0-8-4. And Ward, the team's muscle, clashes with Melinda May as she questions his motivations.

In the end, Coulson and the team are able to defuse the weapon and stop Reyes from using it. However, the events of the mission leave Coulson shaken and questioning his own role within S.H.I.E.L.D.

Overall, "0-8-4" is a thrilling episode that showcases the strengths and weaknesses of the team as they work to prevent a catastrophe. It is full of action, suspense, and character development, and sets the stage for future episodes of the series.
