Input: Skye:  Did you find Raina 's body yet ?
Phil Coulson: There 's a lot of rubble to dig through , but not yet . Whatever gas came out of that obelisk hit you , too . That 's why we 're being extra cautious . It 's hard to make sense of all of this .
Skye: What ? No , it - No , it is n't . We lost . We failed .
Phil Coulson: Skye , do n't say that .
Skye: It was n't because of Hydra . It was because of me .
Phil Coulson: Do n't blame yourself .
Skye: If I did n't go down there , you could have blown the place !
Phil Coulson: That was one battle . This is a war .
Skye: And Ward and my father - the rotten core the center of everything !
Phil Coulson: We did not fail ! Trip prevented a disaster , and Whitehall 's dead . We cut off the head . And while Hydra scrambles for a new _ one _ , I will crush them ! I 'm gon na make someone pay - whoever the hell it is .
