I’m not able to confirm what “grouping” refers to from the current context, so I can’t give a reliable Season 2 timing yet. The search results are too ambiguous and point to different shows/topics, including The Four Seasons and other unrelated “group” references.

What I need

Please share the show name or a little more context, and I can pin down exactly when grouping opens up in Season 2. For example, “grouping” could mean a cast/group split, a game mechanic, or a plot event, and the timing depends on the series.

Current reading

Based on the available results, there isn’t enough verified information to answer this precisely without guessing. The closest matching Season 2 material discusses The Four Seasons and its cast/season setup, but not a “grouping” event specifically.
