Copying and pasting my post from the “afraid of shadows” thread, coz it fits this topic…
Wonder if Rumple left the dagger in SB? He thinks he’s going to his inevitable doom, so I could see him leaving it behind, either because he thinks he’s screwed anyway, or because he has a faint hope that he might get out alive if the dagger isn’t in NL with him.
It could be cool if Belle finds the dagger in SB, and then the name on it changes to PP at some point. I know there have been magic mirror theories floating around too, but the name on the dagger changing would be another way for Belle to discover where Rumple is, because everyone knows that PP is in NL. Of course, she’d think that he’s died if the name changes, which wouldn’t be so fun, but it could provide a wonderfully emotional scene between Belle and Nealfire, (assuming they’re reunited by then).
