A supply chest with ender pearls in it, a pressure plate that stops both of us dead, and an awful lot of cobwebs.
A chest worth having
The episode opens on a chest we approach with justified suspicion, standing well back in case it is rigged. It is not. Inside: a golden pickaxe, two potions of swiftness, two apples, and two ender pearls.
The pearls immediately start generating schemes. Scoti's is the sensible one, keeping them for an emergency exit rather than spending them on convenience, and we drop a chest at the entrance so there is somewhere to leave things on the way back through.
Basket versus the cobwebs
This cave is strung with webs, and without a sword good enough to cut them quickly it turns every corridor into a slow crawl. Basket spends a genuinely large portion of the episode wishing aloud for a bucket of water so he can wash them all away at once.
We still do not have water. It has now come up in three consecutive episodes and is quietly becoming the run's main unsolved problem.
Do not move
The best moment is a pressure plate spotted at the last possible second. Both of us stop where we stand, and Basket describes it as one of those Indiana Jones moments where somebody says do not move and means it.
Past that there is a section closed off behind iron bars, the unmistakable sound of a lot of lava somewhere below, and a warning to watch for tripwire. The map has clearly decided the polite introduction is over.
Two doohickeys and a lot of redstone
Deeper in there is a redstone contraption neither of us can make sense of. Basket has a theory involving something that was meant to be above it. Scoti is not following. The mechanism is left unexplained, which given how the TNT shortcut turned out last episode is probably the right instinct.
Somewhere around here they admit they have completely lost track of how long they have been recording, decide it does not matter because they are enjoying themselves, and carry on. The episode ends with mobs behind us that Basket never actually saw, and an instruction to the audience to go make yourself a sandwich.
