I see! Just talk to the mayor and ask him about the town, there should be an option to ask him about the tent! The quest should then activate, won't spoil anymore of it, but do let me know if you have trouble with it!
ah ok found the tent stuff - seems I thaught the "other stuff" option was to go back in the dialogue-choices and not about continuing the list -.-"
so the two public use scenes were about the leasing-stuff and not about the options while having a character follow you?!
then I guess the sister has no scene - could bring her along but nothing happened
(besides some missing dots at the end of sentences from the mayor - some stuff with the dialogues with the npcs in the tent and during the scenes with mother, jace and gwen felt weird - but it was late and I was tired after a long day and just wanted to test it fast so I rushed through the lines)
