Gabriela's sister....last scene SPOILERS

So, was the last scene in which Gabriela's sister phones the church elder a set up for the next series? A jumping off point to investigate the WHOLE abuse online network that apparently exists?

Was that just to let us know that Benedickt was only the tip of the iceberg and that the "dark web" Gabriela's computer expert referred to when searching through Por's stuff was where a whole network that Benedickt was a part of was operating?

And her sister was abused by one of them--the creepy old church elder?

That was a good ending, if so.
