As far as I know, Sankara is not employed by Maison Mere. The fact that he goes on national tv to insult ex Maison Mere in his capacity & without a clear mandate from Werra, is not a problem Werra must deal with. There is no clear evidence to suggest that Werra sends him to do this job. If Ferre wanted to respond, the wisest would have been for him to also find a proxy spokesperson to do the dirty work on his behalf. I am sure when Lacoste suggested that Ferre acts like an illiterate idiot, he had recognised that he is way too stupid to see beyond the obvious. Werra has kept his counsel and is within his right to disown comments made outside of his press office.
Concerning the matter of Bill; I think you need to give him credit for recognising his failings of the past. I see no reason why you want to continue dragging into the limelight issues of his past bad behaviour. What is important is that he learnt his lesson and is willing to share with Ferre the good advice.
