I think I should be the spy of Uncle Sam, and change to face after this storyline end.
I play some loyal game to make everyone in the Union,even Saalek trust me
but I contact Sam and tell him what the Union try to do and their inside situation secretly,so Sam can have a advantageous position while against The Union .
Finally, someone exposed I'm a spy/ I exposed myself.
this is just the basic concept,please comment if you have any idea.
