I saw it on Twitter but it comes from a gossip site. It is possible that this is a Markle fed piece because it seems there are lot of blinds that look like they come from her.
I dont know the timing of when Prince William found out and when he pulled out of the service where he was suppose to do a reading but the spin was that it had nothing to do with Kate’s health or Kingston’s death. It could be a simple as he had to be near a toilet.
Kingston survived a suicide bombing. dont know details but he may have had PTSD.
Supposedly, William didn't go to that service, because of something or other for Kate or one of the kids and may or not be health related. It's all just dumb speculation.
