>>34089851>>34089870True, sorry. It has been a while.
Still there's no indication the kid of the old notebook was Cyrus, and it even contradicts all we know about Cyrus' character, since he's noted to be detached and weird since a very young age.
Cyrus being the kid from the old notebook is just a popular headcanon, and USUM doesn't seem to hint at it either as his point was
>>34089844If anything, it's possible the notebook was from a kid from the Old Chateau, since that is Rotom's hiding place and Charon's notebook notes "it can stay inside a motor almost indefinitely"
