Shaw suggests changing "even just one variable" in their fight against Samaritan. The Machine in running simulations of possible outcomes (which according to visuals numbers in the hundreds of millions) in the conflict between these two (2) AI systems. The one thing they could have done is taken computer records of these simulations and have The Machine (the "good AI") analyze the transcripts/ records of these simulations and give a report as to why so many simulations were failures.

POI Double Header Part 2
26 May 2016 | by awoolforkSee all my reviews

The moment the great QSO went off the aired the next great edition of POI aired right after it in Reassortment. QSO was maybe a bit better but this was still great, intense plot moving stuff just like 5x07. Once again POI writers using everyday situations and turning them into to cerebral Samaritan based scenario's was on display and very well with the viral outbreak in the hospital and the reasoning behind it.

But Shaws escape arch ( the real one which first started in QSO ) was once again the star here. In many ways Shaws escape arch really was the center piece that makes both of these episodes really go.

There are many things in this episode ( as well as the previous one ) that i won't spoil but if you can watch both QSO and Reassortment as both of these episode were so great. Season 4 and 5 right now are really competing for best episode of POI.
