I wonder what they will talk all alone...
Jokes aside he is going to talk about leadership probably and help her level so it is one more leader when one is out and can help defending the base.
To be honest, they can't continue to stay there all the time. They will need to expand their territory or at least know what they have around the base, specially knowing where is the base of the orcs. After they level up enough and plan several teams they could ambush them and eliminate them all. This could mean the end of first arc and then move to somewhere else and find a new enemy or find civilization or find a way to return home.
