i think you misinterpreted a bit,maybe due to kelly katende insisting on him to thank ferré,he said thanks to ferré but also ferré can thank them for helping him on first album but did not say it in the way that they made ferre who he is today
and also he says he is a bit upset with ferre because they had to meet somewhere one day(the biggest train station of paris i think) and ferré did not show up and the fact he lasted long standing there he had the bad luck of police asking him for his papers(which he did not have then)
his apparent self-confidence(in his gesture)gives a wrong impression(otherwise journalist who have jumped on that and told him he something to fuel polemic
him and ferré are good friends its actually ferré who helped him join maison mere
and about kakol,he says that he used to be a lot troublesome in the past with group members but he seems to be calmer now ever since he is with linda
but also as an addition i can tell you that they have problems since about 20 years now,when teka was in the group royaume lifaki and kakol in kibinda nkoy,they even fought one day at the nightclub djo k used to be a dj in(surely because of a girl) and they never had good relationship from then
