Finally got the Weave scene. Was tough; Gale was at very high approval when got it. Basically, for this, I just bounced to camp with almost every significant approval jump with Gale - so I did not track what and where I did anything as I just wanted to darn scene. BUT, I did get the high approval because I did end up saving Arabell, Mirkon and protected Sazza. So, it is possible to get it at very high (now at exceptional after Weave scene).
Ultimately, I camped after every big moment. As stated above, until this is addressed in the next patch, may be the best way to get it.
I'm just happy I finally got it. I have played dozens of character trying to get this. Thank you!
