Could the fact that in Campbell's old summer house there is both a hidden room of highly morally questionable experiments as well as a torture room have something to do with hwy the government is after him?
I was honestly going to mention it in this ask talking about Campbell’s crimes, but I wanted a separate place to talk about this. Okay, so basically, my thought process was that maybe the whole operation was pretty under-wraps until one of the bigger experiments managed to break out of the lab. The creatures following wave of destruction - which could have not only been what murdered Jasper, but if was able to live long enough, also could have even been what sent Chucky to the hospital with life threatening injuries - was enough to spark government attention.
I have no idea how the government would trace the monster back to Campbell, but once they made the connection, it’d certainly be a good motivation to hunt down the con-artist for questioning.
