The Theory & Red Truths in "Different Topic, Didn't Read" Form:
The chain lock must be set. You're allowed to unset it, but then it must be reset. Unless it is set, this exit of yours will be unusable.
It is impossible to set or unset the chain lock from the outside by any means.
No one was seen in the BATHROOM. Except for one location, Battler does not exist in any place inside the guest room.
Ushiromiya Battler does not exist within the guest room. ......There are no exceptions, including the closet.
Gohda severed the chain back when the crime was first discovered. Since the chain lock is not functioning, it is impossible to use it to create a seal.
Erika repaired the chain lock.
Erika used that duct tape to join the two cut ends of the chain together, 'sealing' them. In other words, the chain was repaired by the duct tape, and this room once again became a closed room locked from the inside.
The lock caused by the chain is intact.
Please, allow me to speak. Know that neither is broken. Know that an unbroken seal proves that there are still none who have entered or exited. It needs no second telling, but know that entering or exiting without breaking the seal is impossible.
This is a closed room created from the inside. The seals on the windows are intact, so there can be no escape from there. Of course, there is no way to escape by leaving through the bathroom. ......I'll make it simple. There is no exit or escape from except for this door. However, the chain lock on this door is set. You can unset and reset it all you want, but you can only do so from the inside. Furthermore, you are free to go out through the door, but you cannot leave of escape while the chain lock is unset.
...Kanon's escape and all the hype for Kanon saving Battler and Erika killing Kyrie follow...
Kanon does not exist in the guest room. .........Of course, this includes all parts of the closet, the bedroom, and the bathroom.
- Hmm... ummm... hmmm... would undoing the duct tape seal, leaving, then resealing it violate a red truth? It was impossible to undo the chain lock before the duct tape, but what if it wasn't after?
- The only other explanation besides taping the chain is someone else going in and resetting the chain then hiding under the bed or something. So.. .two possible ways.
- And from this I go to the duct tape chain. The chain is still set, but red doesn't clarify whether it was unbroken (and resealed). Yes, it's possible for Erika to notice a reseal, but Erika hasn't had the opportunity to. The red truth: It is impossible to set or unset the chain lock from the outside by any means. The ability to unseal and reseal the lock is still an option as both ends are still in the 'set' position.
Also, reading over that last bit again:
know that entering or exiting without breaking the seal is impossible.
This isn't just about prevention. This isn't just a wall that prevents Battler from escaping. It's a vital clue to how he escapes. He cannot enter or exit the room without breaking a seal. Flipping the chessboard over, he has to break a seal to enter or exit the room. Whether or not there were people available to break him out, he would be unable to leave the room without breaking a seal. Breaking a seal is a required part of the exit. To exit, he must break a seal and the only seal that can logically be broken and unbroken is the chain lock. For the chain lock is sealed and the easiest seal to break. It is only a move that is so diabolically devious that only Moooojo Jojo could indeed come up with such a move, for such a move is crafty and clever and daring and powerful just as Mojo Jojo is crafty and clever and daring and powerful! Mojo Jojo will escape from such an inferior trap to set out to conquer the Powerpuff Girls! Hahahahahahahaha!
