Witch Game 5 - The Anniversary

[Fippe94]

Person A unlocked the door, person B entered and killed Stanley, then left, then Person A locked the door again.

[Kuroaitou]

Stanley called a person A (or any person with the room's key, including Natalie) a favor to invite them to their room. Person A dropped a bomb or detonation-based device inside the room while he wasn't aware, alongside the room's key. Upon person A leaving the room, Stanley himself locked the room from the inside, and Stanley's actual murderer (person B) detonated the device from afar, killing him from long range.

Person A unlocked the door, person B entered and killed Stanley, then left, then Person A locked the door again.

This is a clever idea actually, but:

During the story, anyone who unlocked a guestroom from the outside with a relevant key then proceeded to enter said guestroom.

Combine this with previous red truths and you'll see that this scenario couldn't have happened.

Stanley called a person A (or any person with the room's key, including Natalie) a favor to invite them to their room.

I can't really understand this one. Could you rephrase it please?

EDIT: If you meant that Stanley invited someone through the phone, then my previous red truth still stands, because he was not able to let anyone in without a key.

Stanley called a Natalie to unlock the door for them and let someone else in (Person A). Person A dropped a bomb or detonation-based device inside the room while he wasn't aware. Upon person A leaving the room, Natalie locked the room from the outside, and Stanley's actual murderer (person B) detonated the device from afar, killing him from long range.

I should have read further than the first sentence. >_< For convenience:

You didn't see any trace of explosion in the guestrooms. You would have seen if there was one.

[Kuroaitou]

Stanley called a Natalie to unlock the door for them and let someone else in (Person A). Person A dropped a device inside the room while he wasn't aware. Upon person A leaving the room, Natalie locked the room from the outside, and Stanley's actual murderer (person B) triggered the device (which could have electrocuted him, suffocated him with gas, eviscerated him from blades) from afar, killing him from long range.

DOUBLE POSTING BECUZ WHO CARES?

Stanley called Natalie to unlock the door for them and let someone else in (Person A). Natalie then relocked the room. Person A then killed Stanley inside the room, called Natalie again to unlock the room for them, and the murderer then left the room upon Natalie opening it. Natalie then relocked the door from the outside.

[Submachine]

No traps were intentionally set inside Stanley's room. Remote-controlled, lethal devices count as traps in this context.

Natalie didn't lock anyone else than Stanley in Stanley's guestroom during the story.

[Kuroaitou]

Repeat in red: "The phone can only call Natalie within the guest rooms."

[Submachine]

The guestroom phones can only call Natalie's cellphone or Simon's office phone.

Personal request for the host to condense the solved red truths into spoilers (i.e. - red truths that were helpful in solving a part of a mystery should go in a spoiler, while the actual solution in red is left visible). This way, I don't have to scroll through several lines of red text to see what red truths belong to who.

Specifically, the ones for Alfred and Tina.

Done! All redundant red truths in the second post should be in spoilers now. If you spot anything that I missed to reduce or something that I shouldn't have reduced, be sure to notify me about it.

Get those blue truths going again.
