And to finally bring me up to date with all of your line's posts!
Based on his age, I would probably say the ones of mine that are most likely to have any sort of connection to him are Vidar, Seb and Finn. With all of them being older ones who have at times travelled around different places, there is good potential for all of them to cross paths at some point.
Failing that, when he does arrive in town, there is potential with my ones who run or work in businesses like Allie with Pestle and Mortar or Jack working over at Mercy Cove Brewing.
