Senna doesnt need his teammate move over for him. He prefer fair fight, and definately not an inheritor like Alonso!!
Senna actually gave Berger a win at the end of the season as payback for the support he had received from the Austrian, so team mates supporting Alonso is not a discredit to him, unless one thinks it is a discredit to other drivers too. Even the latest saga of Ferrari winning a championship through the courts is not unique. Senna and McLaren appealed the 1989 result at Suzuka to try and secure the championship. Would that have made Senna an inheritor?
Looking through the sport's history, it's amazing how many of the charges levied against Alonso seem to wash over Senna.
