Marc Malkin Senior Editor, Culture and Events Ask the stars of Disney+’s “Loki” if there’s going to be a third season and all will insist they don’t know. “I have no idea, honestly,” Sophia Di Martino, who stars as Sylvie, told me Saturday morning at a “Loki” FYC Emmy screening and Q&A at the Samuel Goldwyn Theater in Beverly Hills. That doesn’t mean Martino wants her time with Marvel to come to an end.
