I wanted to use a temporary joke flag or something to have on my card of season 2, but when does it start? I don't think this has been answered yet, has it?
No one knows. And it seems like no one will know, until it happens.
More importantly, for your case, no one definitely knows when Violet will decide to randomly take the next "snapshot" of NationStates for whenever season two happens.
You will simply have to commit to your "joke flag"
