There is the problem of Dave Kleiman's father too. As we know, he is old 92 years and at least partially informed, concerning Dave's infliction with Bitcoin.

But he probably has no idea, what is Satoshi Nakamoto. And that there is a fortune of half a Billion dollar somewhere jammed in the cyberspace, what belongs to Satoshi's successors, so maybe to Dave's successors.

Imagine.

Its a message, what can kill the old man, if it is delivered false. Heart-attacks exist.

My advice: say nothing or say it professional. Its explainable to the old man only when Ira is in security. Its a task for the psychologically hardened public service. Nothing for good-meaning amateurs.
Its first Ira, then Louis. Both need professional help.

Warning: if Ira is really paranoid, he risks to defend himself with the gun, getting accessed violent.
