Nathaniel's quest

Hello I am currently playing through a game with Nathaniel in my party. (http://www.spellholdstudios.net/ie/nathaniel)

I have only gotten a few lovetalks with him, he has responded nicely to each of them. I recently went and discovered that his ex (?) Latimer had escaped prison but from there on nothing has happened. I have slept outdoors but I cant find any info on what to do. I also bought him cake...

Thanks in advance for any advice
