Vin-Tak:  Sorry . The argument was going nowhere .
Phil Coulson: You back with us ?
Lady Sif: Yes . My memories have returned . I am Lady Sif of Asgard , friend of the S.H.I.E.L.D.
Vin-Tak: Asgardian
Vin-Tak: - well , that explains a lot .
Lady Sif: It is true . We do n't trust Kree . That is why I am here . When Heimdall saw that _ one _ landed on your world , Odin charged me of retrieving him .
Vin-Tak: So you came to pick a fight .
Lady Sif: We know enough about Kree history to be concerned .
Vin-Tak: Well , then , if you know Kree history , perhaps you 've heard the tale of Terrigenesis .
Lady Sif: Of course . Ancient Kree descending on planets , altering the inhabitants to fight their war .
Vin-Tak: And Earth was one of them .
