The episode picks up seconds after Scoti's death to the Rage Pigman Guardian, and nobody is quite sure what happened. "It happened so fast I have no idea." The counter reads Scoti 54, Basket 51, and Scoti's gear is a long run away.
Nine diamonds and a lot of fire
The diamond cave from last time is still on fire in places. On Basket's screen, torches go up along a wall of diamond ore, and one of them reports "I have nine diamonds." Someone also knows where the fleecy box is: to the south. Later nobody can remember whether it was south or west.
Two more for Scoti
The run back goes badly. "They're all splash potions, I can't drink them," and a few seconds later the chat reads "Scoti_Garbidis was slain by Magma Cube." Scoti's things are down by their tunnel, so Basket, still running on fire resistance, raids a chest of supplies to help. Among the gear is a bow named Flame, with Power V, Flame I and Infinity I.
It doesn't help for long. A minute later: "Scoti_Garbidis was slain by Giant." "I'm officially five more ahead of you now." Scoti has no armor, and there's no backup armor chest.
Spawners by coordinates
With a speed potion going, Basket is "moving faster than my game can load, and there are ghasts shooting me," and is "breaking spawners like my life depends on it, mainly because it does." One spawner turns out to be inside the obsidian. A giant shows up in there too.
Things get confusing enough that Basket turns on the coordinates. "I hate having my coordinates up when I record, but at this point it's actually pretty much vital." Basket stands at 113, 30, -966 and is very far from Scoti. Along the way there's a patch of fire to stand in, more diamond, and a silverfish block that gets broken anyway. "Oh, there's too many!" They live. Digging through obsidian with an iron pick takes "a long time," and killing a giant just drops a small zombie.
The hollow box
Their supplies are in a cobblestone box they built near the bottom. Getting there means going past giants, witches and ghasts, and one of them is taking poison damage with no potions left. When it finally comes into view: "Wait, it's hollow, it's just a friggin wall." "There's nothing in here! There's a chest with diamonds and a friggin crafting bench." The rest is down the chute below.
Back together
The last stretch is a speed potion and a lot of yelling. "I see ya, come in, come in!" "I broke a bunch of blocks, you're exposed!" "I don't have any blocks." Then they're in the same spot again. "I think this is the end of the episode, we're back together!" The counter ends at Scoti 56, Basket 51.
