Hear me out on this one. I am 100% positive that the hidden half-pendant for "The Walking Stick of Harriet Tubman" was on an actuator for one of the doors leading from the Swamp to the Dark Forest, but the frontrunner never signaled it.
The pattern for hidden half-pendants in Season 2 is pretty much obvious. It was always on an actuator somewhere.
Now then, given that, we have to assume that it would have been hidden just short of the second guard in sequence
OR between the 2nd and 3rd guards in sequence. Now we know the guard sequence from watching the episode: Crypt, Throne Room, Shrine.
Therefore, it must have been hidden on the Pit/Throne Room door actuator, or on a Swamp/Dark Forest door actuator. And, because you can clearly see that it
was not on the Pit/Throne Room actuator, then it MUST HAVE been on a Swamp/Dark Forest actuator.
Case Closed!
P.S. The location given for the hidden half-pendant in the episode "The Bifocal Monocle of One-Eyed Jack is incorrect!
The Bifocal Monocle of One Eyed Jack: Wrist of camera-left Headless King
The correct location for the half-pendant is on top of the base of the camera-right Headless King. The Clock covers it up as the 2nd runner descends from the Chamber, but it was there. I've taken a screencap from the episode and circled the half-pendant in red for The Ancient Warrior, since he requested it. Here it is TAW:
