That's a very good call, Jack. Souix Falls would tie in with the first series, it would all make sense and you'd also have Lou from the first series, but in a younger guise.
Think that's the only way a second series would work. Guessing if they did that they would have Molly as a young kid.
Now it all makes sense. That would all fit together perfectly. Forgot all about the 'Souix Falls Incident.'
If you like a bit of twisted violence in your drama ,Utopia is available as a box set on demand C4 and re-running currently .New series to follow soon .Didn't watch all of It first time round but set In London IIRC ,so didn't get the Plot but gripping .
