Although I'm sure I'm just being cynical here (everyone needs a hobby) Noah is one of my favorite candidates for narcissistic personality disorder, and the fun thing about that is that every event just has to be about you, including someone else's misfortune. If I wasn't as pessimistic, I'd probably just take it as he says, that JewWario was a dear friend of his and it was a terrible shock to him what happened, and everyone has their own way and time to grief, but this is the Farms, so here I go with some very nasty speculation:
He gets such an abundance of pity out of the guy's death that it just lingers and keeps coming up, same way he has to keep reminding everyone how very depressed and in need of medical attention he is and "these damn doctors are throwing the proverbial book at me!" At some point I just start to suspect that the pity is worth being stuck in the ditch for him. Even the CA-stuff, not just "no comment, please, I don't want to be involved with this" but a "WOE IS ME, THE PAST HAS BEEN CRUEL. I CANNOT CARRY ON."
How long do you have to give someone time to grief in the US before you finally get to slap them across their blubbering face and tell them to move on? This isn't healthy, man.
