Yes, I already referenced this. This was the exception that proved the rule - in the majority of cases, when Rand demonstrated a weave that LTT knew, hand gestures had nothing to do with it (see his Trolloc killing lightning attack in The Stone of Tear, the myriad weaves he created in "Towers of Midnight" and his use of Callandor to create attacks - hand gestures are never used for any of theses). That scene actually demonstrated that Rand was now experiencing Lews Therins' blocks in addition to his weaving knowledge, whereas before, he would just want something to happen and unconsciously be able to recall how to do it.



Incorrect, as I've already shown examples of. You need only look at the use of the Bowl of Winds, the Windfinder Elayne saw, the damane who fought during "The Great Hunt" and any showing by the Forsaken to see that most do not gesture.

In fact, not only did RJ tell us this, this is a specific point made in the books - one of the Wonder Girls explicitly tells us that only Aes Sedai make a throwing motion to create fireballs, but they learned that you didn't need to move your hands to do it and bcause the Aes Sedai learned that way it was difficult to teach them another way of creating the weave.

It all depends on your training. While one group of channelers might use gestures for a certain weave, another group or other individuals wouldn't need to. But, in general, gestures aren't needed - they serve as a mental aid to concentration; think of it as an assisting crutch to envision three-dimensional space.

For example, one of the damane major punishments involves cutting off the hands, specifically because they aren't needed for a damanes' channeling (The Great Hunt, p. 572).

"Interesting example in the later Wheel of Time-books. Aes Sedai have during many handing-downs of techniques been including gestures to the casting to make them easier to cast. The result is that many younger Aes Sedai cannot cast the techniques without them.
Played with even further. Some people claim to be able to tell which Aes Sedai a channeler learned techniques from, simply by the motions. While the Aiel Wise Ones, as well as the Sea Folk Windfinders, can do the techniques without the motions. As such, they are much more efficient and much quicker."

There is also an example of a specific Ashaman who has a block in which he needs to use hand gestures to weave something the other Ashaman can weave with only thought.



Yes, she knew that because the counter-attack was very strong. This had nothing at all to do with gestures or any hand movement. If you look at that section again, Graendal is not described as doing anything but walk, indicating that Verin was reacting to the weaves, not to any physical gesture indicating where Graendal was aiming.
