Thread Meaning: Snopy has just gotten back after 5 years of searching the globe for his missing girlfriend. In that time he has lost touch with a lot of current events, being detached from details that come from being around org leaders or the Gotei and whatnot. Even worse, Shadin is literally the only person Snopy knows who isn't dead, missing, or has amnesia. He's also the one Snopy has the best idea on where to find him (I mean this is Shadin we're talking about, it isn't rocket science).
Direction: Snopy gaining knowledge of recent history, and reacquainting with Shadin mostly. He also is kinda alone right now so having someone to trust or a place to stay is important. He literally has no one and nowhere right now.
Thread Engagement: The most important thing is that Snopy will get back in touch with the events of PH, the current state of affairs, etc. He trusts (albeit it is a cautious trust, cause last time they had a thread Shadin kept to his word and got Snopy his Bankai by almost killing him) Shadin more than he'd trust anyone new he'd meet, not to mention Shadin would have an inkling on specifically what Snopy wasn't around for.
Future Notes: Not entirely sure. Could just be them getting reacquainted. Maybe Snopy would get a place to stay, be pointed to someone or somewhere else that would be of use, pointed to another org, or become a honorary member of the Yayjuu Alliance (I don't remember how the Yayjuu works so I could be off), or something to that effect. Also even if he didn't need it, Snopy would probably owe Shadin a favor.
Extra Notes: Nothing off the top of my head. Pretty narrow start, but considering the circumstance a LOT of different things could happen depending on how the interaction goes. Just putting this here to organize my thoughts + make your life easier.
