*spoilers*how did they know that the memory would work on the bureau's people?

[Anastasia]

I mean they are GP so they supposed to fight the memory serum. They weren't sure if the Gp would forget everything because they couldn't try it on Tris. we dont know if the serum was able to do that on GP.So the plan could also didn't work right?

[Emma]

They probably didn't know. They just did it because they could...I think that's all.

[Anastasia]

so there is a possibility that maybe the plan could probably fail and that means that tris' sacrifice would be meaningless...

[Emma]

Yeah...probably...and that would be awful

[Anastasia]

Yeah like the end isnt awful just the way it is ;p Although I like it... I thought the end couln't be more sad :/ I guess I was wrong...

[Belle ~carry on my wayward son~]

Haha. Um...good question that I will not answer because I simply don't have an answer

[Anastasia]

yeah me neither :)

ikr Anastasia... and questioner, it doesn't say your name for some reason, Matthew had been testing serums forever in his lab, I don't think they would have risked even Caleb's life if they didn't know for sure. Don't you think? Or am I missing something?

[Savannah]

hmmmmmmmmmm maybe they didn't
I mean, if i'm correct, it didn't actually say what happened to the Bureau
as far as we know, they could have been working secretly.
then again, remember in Insurgent with the Peace serum?
If they don't know whats happening, and maybe it makes them not "want" to fight it.
Yeah I'm going with the second answer, haha.

yeah i see what you mean but when they tried the truth serum (i think)and they changed it a little bit so it could work on tris... they didnt make it so good and tris knew that she was under truth serum and she could lie...

Wow nice answer maybe you are right..but are they supposed to know that something was going to happened? that's why David went there.. if they didn't know it then Tris would propably be alive right now... but maybe they didn't know exactly what was going to happened...so yeah maybe you are right...
