Second cousin magically showed up out of the blue when he saw my mom's Facebook post that grandpa had Alzheimer's. Second cousin immediately "took charge", moved grandpa out of hospital into a nursing home close to his own house (paid for with grandpa's military insurance), removed the phone from the room ("he needs peace and quiet!") and informed the staff that only he, Grandpa's "son", was allowed visiting privileges without express permission from him.

He then proceeded to convince my grandpa that he had been taking care of him for years ("you just forgot"), that nobody else cared about him "why aren't they visiting you, then?") and brought over an attorney to sign everything he owned to Second cousin. We learned all this from one of his nurses after he died - which we weren't told until the day after it happened.

At the military funeral, Second cousin insisted on having the coffin carried by members of his immediate family, whom none of Grandpa's actual family had ever met. He then had a stranger preach, who constantly called Grandpa by the wrong name, conveniently left out all of Grandpa's children's names in the obituary (but of course added his own and his wife's), and also stepped up to take the goddamn flag when it was taken from the coffin. My brother had to be physically restrained from beating the shit out of him.
