if Sigma is going to return then he'll clash with the NGR who want him dead this may be interesting

as for the virus both Zero and Sigma are infected by the virus and their souls have bounded with the virus ( this may explain how zero survived after the events of X5 ) preserving both of their lives even if their bodies are destroyed but Zero choosed to be a mavrick hunter and Sigma choosed to go mavrick even Lumine confirmed that Sigma repelled out of his own will
