So, I run another test with new character. It seems to be enough to have a very high approval with Gale and spend 10 nights in the camp to get a scene with a romantic moment.
Here's my step-by-step action:
Shadowheart recruitment
Astarion recruitment
Gale recruitment
Reading Gale's thoughts (tadpole) in the dialog
Camp
Lae`zel recruitment
Camp
Battle at the gate, dialogue with Zevlor
Camp
Will recruitment
Camp
Dialogue dying True Soul dwarf
Camp
Get the dog
Camp
Teleport
Camp
Pet the dog until the approval with Gail reaches very high (I did not do this in a normal game passing, only for the test)
Teleport>Camp x3
The scene
P.S. Of course, I talked to Gale with each new dialog.
I don't know if the tadpole usage on Gale has any effect, I need to do another test to check, but it is too exhausting.
