Last episode ended with the white wool placed and this area's emerald still missing. This one opens with a promise: "We're gonna get this emerald even if it kills us. Probably gonna kill us."
Even if it kills us
A viewer thought they saw a lapis spike coming out of a wall near the center of the area, so that's the first lead. A dispenser turns up holding cursed leather armor with Mending, the kind of trap that puts it on you if you have an open armor slot.
Then a room of ore-head mobs. Someone noticed there was "one of each in all the corners," and the iron one got away. "I'm using my brain, I'm so smart, I'm the best at Minecraft."
Intersection 3
A dark obsidian hall with lava behind iron bars leads somewhere new. "This might be an intersection." It is: Intersection 3, with an ender chest. One of them dropped a single block, thought they were dead because the glass didn't line up with the rails, and wasn't. The new connection is a real help. "That's way more convenient," since until now they had to go through Intersection 1 to reach Intersection 2.
Into the diamonds
Back in the area, Scoti_Garbidis gets the Ice Bucket Challenge advancement, and someone sets themselves on fire. A bed down here won't work, because there are monsters nearby, and a lot of creepers are coming up behind. They get past a magma section and start tunneling toward where they think the emerald block was.
The walls they dig through are diamond ore, on every side. "If we can secure this stuff up there, then we can get a bunch of diamonds easily." There are skeleton noises everywhere and at least one spawner gets broken without anyone being sure what it was. Then: "Here's an emerald block. Yes, you were right, it is over here." The emerald is up by the lava.
A chest full of diamonds
Getting out is the next problem. One of them wants to block the lava and put water down. The other thinks that sounds like a good way to get knocked off and die somewhere else. Then someone spots another chest across the way. "Oh my god, dude, look at this chest." On Basket's screen it's a treasure chest packed with stacks of diamonds and a golden apple. Blocks get ditched to make room.
Finding the way back takes a minute. One of them recommends going down the middle and climbing up past the purple thing. The emerald goes into the ender chest. There's a regular emerald too, and only the regular one went in at first. Chat decides Scoti was right this time.
Emerald 21
On the way back a ghast spawns in the ghast box while someone is still standing in it. "That'll wake you up."
At the monument, the tooltip on Basket's screen reads Emerald 21, Crying Crystal Redux. It goes in, and the chest now holds 21 emeralds. One of them takes a piece of glass from the chest for a house window. Brown is probably next.
