So, talking about Olivia, how can we help her achieve her goals? She has motivations which she pursues, and we could probably offer support. The goal of better magical law enforcement (or, to be more broad, of moving magical human society to some semblance of modernity as opposed to wild west it's at now) is a noble one. I am guessing we could do the following relatively simply:
1) Put her in contact with SI, and Alphas, ie the local militia type groups that do street level supernatural crime handling. Possibly enhance both with IDU. If there's a canine unit attached to SI, enhance the dogs. Speaking of dogs, we should probably offer enhancements to pets of Cauldron members, to turn them into more effective home defenders.
2) Get law books from the Courts for her, and probably Murphy (I forget, did we do something like this for Christmas?) ir order to help set up more efficient policing
3) Set her up with some resources to start doing stuff
4) At some point soonish spend an AP on Order of Cauldron / Paranet setup.
We probably don't have time in the next two months, but after that it might be viable. We have school, finding new dwelling for Rosie, crafting for Archive and others as obligations next month. The three remaining things are most likely to be taken by White Council traitor purge, solar and abyssal exaltation handling (probably the prep. stage only), and helping Lydia find a powerful dog to further boost or meeting the Alphas. The month after that we have School, horror-con (if I remember correctly), possibly remains of crafting debt to handle, possibly continuation of exaltation handling, probably Flick's expedition (either setup or the whole mission, if it can even be organized so swiftly), and maybe we get the last slot free. We have a rather packed schedule with lots of stuff we can't delay (much).
So what exactly are we looking for here? We have more to work with when doing personal investigations, but the goal changes the angle we approach from.
Are we recruiting? Looking for details of a dead plot? Stealing the well? Are we committing to a local presence to exploit this resource?
Showing up and playing hardball seems counterproductive in all the paths I see. If we just want to pump him for information we can ask questions on the stuff we care about using Karl and his dogs. If we're looking to move into town in any capacity having a local tainting our reputation would be a pain to clean up. If we're actively recruiting then it'd self evidently sour our working relationship.
Well, personally I am here for the information, and if there is something nefarious going on, then either helping the guy, or bringing him to (non-lethal most likely) justice. I definitely was a soft sell first, as a setup for cauldron's expansion into the area and transformation into the paranet.
Maybe talk shop with him about alchemy?
