Minecraft wiki entry for 5CHP, associated text: As Jake and Emily stare at Tank in silence, Tank reiterates that PacificViv is her younger sister, Vivian. The three then head over to Tank’s apartment in the west tower, where Ba greets them. Ba mentions that he got hired at the convenience store where Tank used to work until he got community service, and Ba also mentions that Mr. Mishra has his own workshop where he builds robots. Tank is excited that Ba has another job now, but Ba soon leaves for work. Tank then introduces Jake and Emily to Vivian. Vivian shows Emily her world, while Jake shows Vivian a screenshot of the world on the apartment’s LAN network. Vivian seems interested in helping them, and the four soon head back to the computer lab at the community center, re-launching the world and showing Vivian the redstone circuitry. After some trial and error, Vivian is able to successfully open the wall leading toward the castle. The three (Jake, Tank, and Emily) then prepare to enter the castle.
