Since going north will be 6 months later, so elin and the queen will be absented at that time as they are closed to give birth, maybe also lia as she just has her wedding and not allow to travel by her illness, so what's left will be only the wife going with us, maybe cass too if you are on green path.
I think next update will have time skip 6 months later, we will focus on lia's wedding most and maybe some content for arcadia and elin's friends since they are few content or missing in this update and I doubt they will go north with elis too, if not then there will be no time for their contents.
Then, in the final of 0.13 we will start to go north and arrived on 0.14, remember aurora said she has a younger sis and marriaged big sis during the lunch meeting? We may have as sister harem after all.
