Yeah, all of that, Jay.  Couldn't help reflecting on much of what you say, myself.  I came to this conclusion: 

There must be a legal firm in Edmonton (probably more than one) which might benefit from Beaver's abilities ("I’m good at absorbing, understanding and repeating information.") as long as he was kept at arm's length from  clients and courthouse (the Law Society may make that part easy.)  Create a niche for him, give him an office and access to all the legal libraries.  Sort of a "paralegal plus" as it were.  The closest he is allowed to get to a case is the boardroom meetings with a specific legal team.  

A portion of his pretty-decent-salary (somewhat more than a typical paralegal's) was allocated by the firm to pay debts in an "orderly manner."

I am quite positive his is not the only brilliant mind out there.  Put him to work, guys and gals, for the benefit of all--including himself, if he is able to distance himself from his demons.
