You did great, Helen!
Nuru, as Helen has shown, and I have tried to with Ædegard, it depends on the individual, but there is one overriding theme:
Tharonwe wants the quest to fail. To that end, he will attempt to read the thought of each individual, and use that thought to his advantage.
Ædegard clearly wants to be done, and
Leafa has shown herself to be quite willing to go wherever Ædegard does, especially since he has agreed to go to her Father to ask his permission on their union.
Nethwador and
Bellyn have now revealed
fear at the loss of Amroth as their area of weakness. Tharonwe can't get them to stop thinking about Amroth, since Amroth has touched Nethwador's soul deeply, and Bellyn's soul has now been touched in turn by Nethwador's, though not as deeply. So rather than forgetfulness a la Ædegard, Tharonwe will try to nudge N's and B's fears toward despair.
Mellondu is clearly angered at Amroth over the treatment of his sister, and Tharonwe's course with him is clear: keep that anger boiling, or cooking at least, so that it hardens on that "anvil" into resolve NOT to allow Amroth to come out.
Mellonin has exhibited a strong desire to have Mellondu and Raefindan with her back in Minas Tirith, and for life to return to normal with her real and adopted brothers. Tharonwe will stoke that desire.
Raefindan has allowed himself to get into a pickle about his personal anachronism. He refuses to act or speak any more than necessary for fear of influencing this time and place in the wrong way (butterfly effect). I, um , forget what it was that Tharonwe hypnotized Raefindan to forget.
Can anybody help there?
Liornung's sense of right and wrong would suggest that he has a problem with Amroth for allowing the women to have been left captive to Tharonwe. Would he consider that to have been wrong? Would he consider leaving Aeron behind to be wrong?
Who have I missed, other than the Elves, who are (not entirely) immune to Tharonwe's osanwë? They are immune to hypnotism, but not osanwë. Think you that it is not so?
