One thing confused me or I missed something. The Kree said he came to Earth after getting the signal from obelisk used by Raina and Skye. We know there are other Inhumans so the obelisks that were supposed to be in the chest were used too I assume - why was he not aware of that?
Another thing, which is based on a number of assumptions:
- I'm assuming Sif will be not harming/imprisoning the Kree and will take him back to his planet,
- I'm assuming he was not working incognito and is not the only one aware of the signal,
- Even if he doesn't remember anything, when he comes back to his planet I'd think others would guess he failed, so what's stopping more Kree from coming?
Feels like they either closed that plot hastily or have more plans for it.
