Team B.S. searches the dark nightmare room by room and finds dead end after dead end. The bed won't let them sleep, and an Enderman and a Psychopath end the episode.
Team B.S. takes on Vertigo, the second nightmare: a glass floor full of holes over the void. Scoti falls out of the world four times before they wake up.
Team B.S. fights through the rest of the spider nightmare. Rage Spiders kill Basket and Scoti, and Basket finds the way out under a lake lit with glowstone.
Team B.S. tests the brown wool in the other Nexus, finds a pit down past the spawners, nearly loses the wool on the ground and fights a ghast on a lava island. Nobody dies.
Team B.S. clears a nightmare copy of its own base room by room, past doom signs, rage creepers and a Brute, and takes the enchanting table. Nobody dies.
Team B.S. makes a run for it across a lava-lit mushroom cave, gets walled in by a teasing sign, bridges the high ground and ends up right back where it started. Nobody dies.
Team B.S. finds the brown wool in a Mushroomania chest, gets thrown into a hall full of rage creepers and a Brute, and Basket picks up Gabriel's Justice. Nobody dies.
Team B.S. teleports into Mushroomania, opens a chest holding the Mycelian Boots and a Mushroom Extract, and learns the hard way what the spores do to your head.
The last arcane key still won't turn up, so Team B.S. trades the Sunken Colony hunt for a trip to the monument, sets Emerald Block #8 and opens a chest holding the Symbiotic Blade.
One arcane key is still missing, so Team B.S. searches every dark corner of the Sunken Colony. The only switch they find is one they already pulled. Nobody dies.
One arcane key is still missing, so Team B.S. rereads the objective and goes building to building in the Sunken Colony. A chest gives up the Crystal Mattock, and a witch gets Scoti.
