In patches they expanded Nettie’s and Halsin’s dialogue to make it more clear Tav wasn’t going to change right away.
In patch 8, Halsin told my party to slow down and enjoy life after we freed him. I don't know if it was because it only took two or three days or if it's because Tav hadn't bothered consulting Nettie or talking to Kahga. It felt like the developpers were talking to me directly, because Halsin doesn't have an in-game reason to say that...
