I don't get why they won't do it. It's an older show, but it's NOT a rerun and it's NOT like they couldn't yank it whenever FLCL is ready to premiere, and then when it's over, CONTINUE IT! There's NOTHING that says they HAVE to air all of the episodes of Lupin in a row! Just ask Hellsing Ultimate, InuYasha: The Final Act, Dragonball Z Kai, Gurren Lagann, or practically any long-running shonen that took multiple weeks off for a Month of Movies or a pair of marathons in a row! Hell, Toonami could also package it as a "mid-season finale" when the last episode of Lupin would premiere before FLCL replaces it. Then again, would Lupin even get topicals? It would probably be expected if it were at 11, but not at 1 AM or later, including its planned timeslot of 2 AM. That's WAY too late for topicals!
