I dunno if they’re important among the Jason Todd fans, but Detective Comics 571 shows Batman picturing his worst fear to defeat a new drug created by the Scarecrow. His fear was Jason Todd’s death. Also, in 573 & 574 there’s a two part story where Jason gets shot by the Mad Hatter and Leslie Thompkins has to save him while The Batman waits and tells her about some of his years preparing himself in college to become the masked hero. The cover of 574 shows Batman carrying the body of Jason Todd. These three issues may be seen as premonitory to Jason’s death or interesting coincidences. The issues are written by Mike W. Barr, drawn by Alan Davis, inked by Paul Neary and colored by Adrienne Roy
