Skye gets alien powers from the ruins. Rana becomes an ugly porcupine. Adrienne Palicki's character and the big black guy (not Tripp as that black guy is dead) are working undercover as SHIELD betrayers. Fits knows about Skye's changed DNA. However, he substitutes her DNA samples with her old samples so that Simmons doesn't suspect changes in Skye. Rana is taken away from a faceless guy as she is about be to captured by SHIELD operative officers. Rana's suicide attempt becomes a second chance at life. Adrienne Palicki and another SHIELD kill many of the Hydra top level leaders. Skye's Dad is happy at the opportunity to see his daughter after Rana tells him that Skye's physical appearance remains unchanged.

Why are Bobbi and Mack looking for Coulson's toolbox? Do they work for Hydra? Is Nick Fury giving them orders to watch Skye? Are they working for Tony Stark because Stark wants Coulson's toolbox?Perhaps this part of the story set it up perfectly for Age of Ultron, Civil War?

Hunter knows that they're up to something "secret" but doesn't seem too concerned about it.

I doubt they are working for Hydra. I think Mockingbird and Mack might be working for either Talbot / Fury & Maria / Hawkeye or Tony Stark.

inhumans baby! Just reveal it already!

Lady Sif loses her memory temporarily when a Kree warrior touches her with a truncheon in Portugal during a fight. SHIELD's agents go to Portugal to investigate. Mack, Hunter, and Simmons do an investigation of the beach area where Lady Sif and the Kree were fighting. Coulson and Agent May help Lady Sif regain her memory of the details of why she is on Earth to fight the Kree. It turns out that the Kree saw an activation of one of the Diviners. The SHIELD team capture the Kree after he fights Bobbi and Skye. Skye's telekinetic powers are getting stronger, especially during the fight scene with the Kree warrior. The Kree's truncheon touches Lady Sif so that she regains her entire memory. The Kree warrior explains to Coulson, May, and Sif that he is on Earth to destroy the diviner. He goes on to explain during Earth's ancient times that the Diviners caused terragenesis among humans. These humans are considered dangerous by the Kree and Asgardians because of their strong powers, and their abominable appearances. Simmons reports to Coulson that the crate that the Kree was carrying is empty. All the Diviners are missing. Coulson said that the things are safe because the detonation of bombs in the lost city should have buried all the Diviners. When Skye is questioned during this discusson with Kree, Coulson, May, and Lady Sif about the whereabouts of Raina, or what she saw about during the terragenesis in the lost city, Skye gets very nervous. When Skye loses control of her nerves, her telekinetic powers begin to emerge. Windows break. Things start shaking. Skye confesses to Coulson, Mae, Lady Sif, and the Kree that she is the cause of the damage around them. She panics by saying that she cannot stop the powers. Coulson and May do everything they can to protect Skye from the Kree. When the Kree gets into a second fight with Bobbi, Fitz gets a powerful gun to immobilize the Kree so that Bobbi can use the truncheon to wipe out the Kree's memory. Meanwhile, the underlying story behind Bobbi, Hunter, and Mack is interesting. Hunter decides to take a full time job with SHIELD. Hunter and Bobbi get intimate in bed. Bobbi and Mack have a heated conversation where Mack convinces Bobbi to ward Hunter's romantic advances away so that he doesn't blow their plan. Mack says that when they "pull the trigger, he doesn't want to see Hunter kill her (Bobbi). Bobbi tells Hunter while she is doing tests on the truncheon that they need to slow down the pace of their relationship. May is able to help Skye control her emotions momentarily so that her powers do not harm anyone. Skye is placed in an isolation room on the plane. Once Coulson convinces Lady Sif that Skye is safe to Earth by staying with SHIELD, Lady Sif take the Kree back to his own planet. Lady Sif does warn Coulson that Asgardian sciences leads here to believe that there are forces in the universe that nobody can control or change. Coulson replies whether she is talking about "fate". Is it fate that a map of the lost city was placed into Coulson's DNA? Is it fate that Skye has these powers? Coulson's memorable line "Where Skye goes, death follows." The second last scene has Fitz defending his actions to his team of not telling them about his knowledge of Skye's terragenesis transformation. Simmons tells Fitz that because Skye is their friend, they would help protect, not lock her up as a threat. Mack voices his concern that the SHIELD team really needs protection from Skye. Skye hears Mack's comments and walks away angry. Skye goes back into an isolation room on the plane. The last scene shows Hunter confronting Mack to demand the truth behind his secret plot with Bobbi. Hunter tells him that "Coulson would be very interested to know about a flash drive." Hunter demands Mack to tell him what is the "backup". Mack denies anything about a secret plan with Bobbi. Mack takes matters into his hands by putting Hunter into a headlock. Hunter goes unconscious.
