An idea for a JA3 Elliot reference, maybe some other references that are humorous maybe:
Ironic references, so really unexpected out of character references for bad characters from JA2.
Example: Elliot's hospital for children or something, which by itself is very ironic and unexpected that he'd go from like a bad character in ja2 to like a benevolent philanthropist (though maybe that wont work out time line wise).
Or the mean lady who ran the factory, imagine she's still mean but like a local newspaper gives her an award for hunane treatment of workers and its clearly not humane or something, ccould be very funny.
