Cole is about to become the primary care-giver of Barb.
If children were legally obligated to provide for adults in old age, there'd be no escaping abusive parents. Snorlax isn't entitled to shit from Cole Smithey.
No one cares about Chris's half siblings via Bob. I'm a retard who read way too much of the Cwciki during the Golden Years and when I think of Bob Chandler's extended family I think of John Kerry because someone photoshopped him with Chris. it was something about Chris attending a wedding? I dunno even know anymore.
Bob's first kids were well into adulthood when Chris was born. The reason Cole Smithey became a little sideshow in the great circus of Christory is because he:
1. had a relatively significant online presence.
2. has a little bit of Chris in him.
3. the emails, which gave insight into Barb, Bob, and the conditions that Chris came from.
When GenoSamuel asks "what made him this way? what is the attraction? what keeps us fascinated?", Cole Smithey's information about Barb provides some answers. He's one of the few primary sources on pre-2007 Christory and even Pre-Chris Christory. Of course he must be taken with a grain of salt, but many of his claims make sense, and his biased claims are easy to unwrap.
Although we don't know as much about the half-siblings on Bob's side, the lack of information on them is itself notable, especially when contrasted with Cole Smithey. Bob's children were an ophthalmologist and a mathematician. Their relationship became strained, perhaps due to Bob getting involved with Barb. The daughter did not attend his funeral. Cole, meanwhile, is a movie reviewer with a youtube channel that only got around 10k views per video, and would've averaged 1k views if not for the Chris connection. From this, it is implied that Barb was the worse parent. It's also interesting because Cole believes Barb drank while pregnant with him. That means she very well may have drank while pregnant with Chris. I wish we had confirmation of that, because it'd explain a lot about Chris's behavior, but I don't want to jump to conclusions. It's always seemed like Chris had some worse problems on top of autism and FAS could be one of the big ones. It can affect a person's sense of right and wrong and puts them at risk for autism, adhd, and general dullness.
