well i would say they may have hinted since 3.0 as the ninja questline ends with Yuki saying she is sending a letter to Oboro's elders back in Othard which to me means the ninja questline for 4.0 was going to go in 2 ways

1. Go to othard with Oboro to face the truth of lying to them to remain in Aldernard
2. Be on the run from the village helping Oboro live a more free life honouring tradions in his own way

Before they revealed Othard i was thinking the latter now i'm thinking the former my opinion ofc
