Basket breaks into a mineshaft, gets chased off by a creeper, spends the day looking for a teammate on the surface, then comes back to clear the tunnels alone.
Season 11 starts with everyone alone and an olive branch in hand. Basket hunts for a teammate, then stops to fix the command blocks when the first pair cannot join up.
Season 10 starts in an amplified world where the water has risen. The Cave Prospectors get diving helmets, cross a frozen lake and dig in under the flood.
The Librarians set up bookshelves around the enchanting table, argue over which enchants are worth it, mine a floor of obsidian, and build a Nether portal.
