I'm picturing something along the lines of Martin/Lewis, where Hans is Dean Martin and Lenny is Jerry Lewis. Lenny is the wacky comedian everybody loves and hits it big in the sims, while Hans is the straight man that drops out to pursue his singing career. By 2072, Lenny is hosting charity events and a mutual friend brings them back together one last time.
Now, the great thing is that the runners have to protect Hans since Lenny's charity runs on live trideo, broadcast by Aztechnology. But the Azzies don't want Hans appearing since he's a bit mouthy about a former deal the two performers cut together back in the 50's which resulted in the accidental poison deaths of a couple dozen ork kids in Redmond. Lenny felt it was an accident, but Hans had some 'runners check it out and discovered that there was some "inconsistencies" in the medical examiner's reports about the levels of harmful agents in their bodies. The only thing keeping Hans safe right now is that he's got the info, but has never shared it with anyone, even Lenny. The Azzies suspect (rightly so) that Hans is getting back with Lenny to give him the evidence live and on-air. Especially since the "accident" is what inspired Lenny's charity work in the first place.
