From what I gather, S'T granted access to the True Power to all his Chosen. So far, we've only seen one of them actually use it (Ishamael/Moridin).

My question is... can weaves of the TP be "seen" by others with TP abilities? Those that can channel saidin or saidar can see weaves made with the respective halves of the True Source.

Moreover, they can also sense the ability and strength in the One Power (e.g., Moiraine sensed Egwene and Nynaeve's saidar abilities and strengths; Rand senses Logain's abilities and strength in saidin). Does this ability/strength recognition apply to the True Power as well?

You may have guessed where I'm headed with this line of thinking... 2 things come to mind:

1. Demandred remarking that Moridin must be using the TP exclusively. Wouldn't he know that if Moridin was holding the TP? For that matter, since there is one part to the TP (unlike the TS), would e.g., Graendal be able to notice, too? We know Moridin likes to hold the TP just for the rush.

2. Semirhage's death scene. Wouldn't she realize Rand could channel the TP?

Just curious for thoughts.
