The deaths sidebar opens at Scoti_Garbidis 127 and BasketMC 96. Team B.S. is still in Trinity Caves, the sand-and-sandstone area over lava where nearly every chest has TNT packed around it. Last time they started setting it off with arrows. This time that's the whole plan: "get ready for lag, man, I'm gonna shoot all the TNT."
Up the spirals
They split up. One of them climbs a spiral ramp ("I'm heading up one of these spirals") and finds blazes on the way. Basket opens a chest crammed with TNT and takes an Ender Pearl out of it. One of them finds a chest with a bunch of iron blocks and leaves it shut: "even as a trap chest I'm not gonna open it."
Up top there's a sign and a trap door. "I'm really curious about what might be down in there." The chat then reads "Teleporting to: The Nexus," and a little later "Scoti_Garbidis Teleporting to: Trinity Caves." The trap door is a way home, and the sign by it says as much: "back to the Nexus is what that sign says."
Finding each other is harder. The two trade coordinates ("I'm at 771") and a water bucket gets placed as a way back up, which later surprises the other one: "Oh, I found your water." "Yeah, it's drowning me."
Bridges and blazes
From the top of the towers they pick a direction and bridge across. Blazes keep coming ("Yeah, dude, there's a ton of blazes"), arrows run out ("I'm out of arrows"), and the TNT goes off one stack at a time. Every blast brings lag: "I got such bad block lag."
Then they spot charged creepers on the floor below a bridge. "Let's see if they're invincible." The plan is to run across and not fight them, and Basket's Ender Pearl is the backup: "I'm just gonna ender pearl." Somewhere past it, one of them reports, there's "a sign to the right of it on a chest."
Blown up
Basket doesn't make it far. The screen goes red, and the chat reads "BasketMC was blown up by Invulnerable Charged Creeper." The sidebar ticks to 97. "I'm at the checkpoint. There's a ghast."
The run back has its own surprises: "Oh, there's a bridge here! It's made out of sand and gravel and I'm running!" "These ghasts are a problem," and "lots of witches." One of them goes after the spawners, and more TNT gets set off on purpose. "Okay, you're blowing up TNT?" "Yeah!"
A T-intersection
They meet up again at the T-intersection with the signed chest. It only holds a water bucket. A chest further on is better. "You're not gonna believe what I got... an emerald." The same run also turned up a pair of iron boots that one of them reads out as "Flame Trail" with Fire Protection III, Thorns III and Unbreaking V. Neither item is shown on Basket's screen.
With the floor sloping back down and more towers ahead, they call it. The chat reads "Teleporting to: The Nexus," and the two stand side by side in the Nexus to sign off. Nothing plays after the credits.
The sidebar closes at Scoti_Garbidis 127 and BasketMC 97. Scoti doesn't die. Basket dies once, to an Invulnerable Charged Creeper. An emerald turns up in a chest, but nothing goes on the monument this episode.
