And of course I'm also confused about the beacon. They set it up to trick Coulson and co... but was it intended to trick them into thinking it was summoning the Kree ala the future? Or was it just a convenient bit to make us assume it was connected to the future bit. IE Did Hale and co. know what the beacon meant to Coulson as such? (Presumably not but man that's very coincidental)
I hope Elena doesn't continue to keep the stuff future her told her secret at this point. It already didn't make much sense to not bring it up. But here we are.
