UrsusArctos: This is a straight reference to the Japanese title of Episode 03, where Shinji wouldn't get so much as a call from his classmates and Toji memorably started to dial him at the end of the episode before stopping midway. Misato used to be in the same position as Shinji - the only calls apart from Ritsuko were work calls - but she now has nobody who will call her since all her friendships are a shambles, and the only man who would have said "I love you" or, perhaps more accurate to Evangelion, "I needed you" is now dead.
