WestTxTapper said: There's also a theory that Remilia is the one who gave the pocketwatch to Sakuya in the beginning. We could be seeing a time before Sakuya came to work at the SDM.
Doubtful, the way Remilia is looking at the pocketwatch is like she misses Sakuya. Otherwise, she wouldn't be looking at it like that. But that's my guess.
