Americans TV show my wild prediction for last 2 ep

the son is the one who killed his parents and sister.

the crazy gay american psycho told the red head that he's looking for the person who killed his "friends" and the red head was meeting with the boy with out having to hide her identity so he had to know her and who she was.

so that's my wild crazy prediction

also the conflict between paige and her parents is all pointing to philip and keri russell finding out the russians used the son to kill his parents.

and the Get jarred out message from the red head on the toilet paper roll shows that he is important to the russians for some reason.
