People just think about this: so the good aliens through Courtney stating that:
1. We are theirs relatives
2. We are theirs comrades
3. Close friends and family members
Ok, but how exactly they came up to such conclusion?
Imagine there exist bad , very bad interstellar government, and they dump all "bad citizens" to Earth, but do they have any records or it just done by cruel way?
Lets assume there no records about, but how those good aliens identify somebody from theirs "tribe" ?
It gets even worse, ok somehow they found out who on Earth is theirs high ranking commander , would they not be interested to keep him or her in shadow, because of possible secrets and possible outcome should the secret info accessed by enemy.
In such case, keeping somebody without memory is a good choice.
All Earth surrounded by soul catching machines and those good aliens have no ways to disrupt those machine, which means its beyond theirs capabilities to reach it.
I mean its hard to believe , that they are no capable of doing that.
They dont wont to start an open conflict, somehow they are not ready for big war in our region of galaxy, again i highly doubt they motivation to go into open war.
When i consider all of that, once again i have strange feeling, that those "good aliens" hidden the truth, they telling us only one part of truth, so Courtney you should be on alert and have clear mind when you talk to them, you need to make sure that aliens would understand , time for meditation is ending a technology exchange must happen, we waited for god knows how many ages to get into such level of communication , its time to deliver on promises.
