In my gameplay Shadowheart was flirty because of some of my actions.
Like not giving up Aastarion and other random events like it in the druid camp. So I naturally just chose her but it was so odd that everyone in the camp was giving me the the googoo eyes even though I barely exchanged 10 words with them. Especially Gale.
And with the Tieflings being so happy and grateful there was no option to try to seduce one or two for some private fun time.
That would be far more believable than Gale's "u want sum fuk babe?" Line. Lol.
side with the goblins and you get another bang option
