I seem to be stuck at the Pet Owner on Arellarti Station. Praising his pet and chatting does not reveal the next step. Nor can I get Tris to do the public walk. What am I missing?
The trick is indeed to have Tris accompany you and then talk with the pet owner. I think I described the conditions for the pet walk in the walkthrough in Tris section.
Let me know where that was unclear so I can improve the walkthrough document.
