(Respectfully snipped.)
You're right, there were some positive, hopeful messages about Bob initially, but the time it took for antagonism to emerge was not that long.
On 6 Aug 09, R posted on IS that Bob "had been very bizarre and secretive since our Mother passed away last year", and on the same day suggested that her father 'bit off more than he could chew'.
On 9 Aug 09, R posted on IS that the barber (since cleared) "bilked our Mother's Blood money -- money D could certainly have spent to improve the conditions of Mom's care, but refused to".
On 9 Aug 09, R posted on IS: "Why wouldn't he take his friggen dirty $$$ with him, then we wouldn't think we were expected to properly manage things in his absence. Also, if he did this, it is cruel to Fontelle and unforgiveable (sic)!"
On 9 Aug 09, R posted on IS: "He pushed his family away and became even more secretive. We now know more about what his single-minded secret was that IMHO he was so ashamed of as to push family away. Definately (sic) NOT the same person we remember going to church when we were little, only to end up selling out to the devil IMHO."
In short, the hopeful messages were quite quickly overwhelmed by and washed away with antagonism and finger pointing.
