Alright after a bit of testing, here is how I triggered Gale's Weave scene a couple times in a very streamlined "race to the finish" manner:
- recruit everyone, camp 1 "go to hell", neutral approval, Astarion stalking off
- camp 2 before entering Grove, "mirror image", neutral approval
- [hero moment] grove fight, diffuse zevlor situation, speak to him
- [hero moment] speak to kagha, save child, medium approval
- camp 3 "trust you"
Here's where it got tricky:
- camp 3 "trust you"
- [hero moment] protect sazza (I left her in the cage), high approval,
- camp 4, nothing from Gale, neutral SH convo
- travel westward and encounter boar
- camp 5, nothing from Gale, neutral Lae'zel convo, Astarion reveal
- cross bridge and go into the forest past the bodies to find scratch, talk to him
- camp 6, Gale weave scene
Things noticed:
You do have to do 2 "hero" actions in the Grove to trigger Gale's "trust you scene" at medium approval. And doing a third will get you to high approval. Although after doing the Nettie scene, it will trigger the Raphael scene because you've forwarded the Search for a Healer quest, which adds another cutscene to clear in the queue. I love Gale's reaction in the Nettie scene however.
After getting to high approval, it really is just waiting for the camp cutscene queue to empty out, but also the fact that camping in the same place does not move the queue. It seems like you don't have to find a new area to zone into, but that you can't camp in the same zone without leaving it and coming back. I did not test this idea reliably however.
It took me two nights of camping to get the previous scene as well (where you learn about his condition), probably because Astarion interfered. Examining the boar triggered his camp scene, so Gale's was apparently postponed.
This seems to be true. When I camped and skipped partymembers with ! exclamation marks, they just showed up again the next time I camped. Also, while what I outlined above in this post was the most reliable to replicate, there was another situation where after camp 4, I zoned out of the Grove and camped again - getting Lae'zel's scene (which seems to strangely duplicate outside of (!) exclamation mark convo). Then I walked on to zone into the 'Forest" region, but stopped before getting too close the dead boar on the road. When I camped then, I got the Weave scene before getting Astarion's reveal, Raphael's scene, reaching Scratch or the Blighted Village, or even getting the camp to upgrade to tents.
Additionally, when I recruited Wyll, he also had a scene that needed to be "cleared from the queue", but I got to skip that since I didn't recruit him for testing.
I know they are still tweaking this, but on the one hand, I don't think we should be able to get this much approach in this one area unless we're supposed to be taking a much slower pace when encountering the Grove. And on the other hand, if you don't do any of the "hero moments" in the Grove, doesn't that mean it would lock you out completely from his romance because you have to unlock his "I trust you" scene?
If patch 4 is still a long while away, an easier way to make sure you get these scenes without min-maxing is to camp after every big moment - in particular if it has something to do with the tadpoles, finding a healer, getting a party member, or if its the first major event in a new area.
