Let's say Rhue is killing Jeruh in the above picture, and Serena has fallen into the water and is drifting off, who is the person standing in horror?
Also, if Serena is out to kill Rhue, would she be any of the females that have already showed up? Like Scatha maybe, because she said in the Pits in E3 that she thought something was different about him besides his name.
Coincidentally, Gaius said the same thing in E2 after they came to Lide. Guess Gaius might be the onlooker in the above picture, then.
I don't know about Rhue's absorbing of Jeruh's aura and his memories getting erased. He absorbed the auras of Cade and Jed too and that did nothing to his current memories except maybe add to them subconsciously. Although he did forget everything that happened after Jopaga injected him, but that could've been the result of the drug.
Also, why wouldn't the PS have retaken control of Rhue's body by now? Because he wakes up everytime he gets close to him? So that's why he is approaching him so slowly, he's afraid to wake him up.
