Well, that could mean anything.
Like
afterlights I believe they only took down one part of the organization and there's a lot more going on.
Well it was stated we will be having
new adventures, so thus I assume the business with the organization is done (since that is the old adventure). If we are still looking into the same organization in the second season, then it wouldn't really be a new adventure, just a continuation of the old adventure.
Plus with the time skip, I assume a lot of time will pass (you don't use time skips for small amounts of time). So with that, I'm thinking all that old organization investigation stuff will of been dealt with during the time skip (since it's just some small clean ups left), leaving a new adventure for us to deal with in the new season.
That's just my thoughts at least. Why mention a new adventure, if we are just going to continue the old adventure? Why even have a time skip then if we are just going to pick up where we left off at? Just wouldn't make sense to me.
