Just noticed this. On page 124 of Bionicle Legends #5, Inferno, Tahu says to Axonn:
Where we have to go, they can’t follow. What we have to do, they cannot be part of.
Nearly verbatim from a quote by Rick to Ilsa at the end of Casablanca:
Where I’m going you can’t follow. What I’ve got to do, you can’t be any part of.
Coincidence, or an intentional reference? If so, might be worth adding to the wiki under “trivia”, like how the Biosector01 entry for Federation of Fear mentions the “Jaws” reference.
