101 thanked Charon and approached the keypad to punch in her pilfered access code. There was a loud squelching sound as the long-unused gears forced themselves into moving. 101 looked up at Charon and tried to suppress an amused smile when she saw the intensity with which he was watching the Vault door slowly back up and roll out of the way. Of course he was curious, she supposed. This was the first Vault they had encountered together that wasn't sitting wide open. In truth, neither of them knew what to expect on the other side. 101's heart dropped a little when the interior was finally revealed.
Another Vault left in total disrepair. Vault 108 had taught them that "disrepair" didn't necessarily mean "uninhabited" so they proceeded with some caution. Vault 106's impact on 101's story has very little to do with the handful of insanity-driven residents, but everything to do with what had driven those residents insane in the first place. This Vault did have a few working terminals, but those were fairly useless. Entries limited to a handful of uninteresting official reports (repair, medical, security, etc - nothing out of the ordinary) and gibberish which she assumed was just corrupted data. They continued onward towards the maintenance room.
"What was that?" 101 asked, slightly alarmed. "What was what?" Charon responded. 101 didn't notice the anomalous response and pressed, "everything just went purple." "No, it didn't..." Their first true conversation and 101 was too freaked out to register it. They continued even more slowly through the winding halls; Charon visibly concerned and 101 stifling a scream when everything turned purple again. It wasn't just purple. Everything looked new. Then, in an instant, everything would return to it's normal, decayed, full-color state again. 101 thought they must have gotten turned around because instead of finding the maintenance room they ended up in the Vault's clinic.
"DAD?!" 101 rushed towards the figure, but as she reached out to grab him everything returned to normal and he was gone again. You may be interested in knowing that at this time Charon considered, briefly, asserting himself by suggesting they leave this, to him, very normal Vault that was obviously distressing his (friend?) employer. 101 had already forged ahead so he pushed the thought aside, opting instead to keep a very close eye on her.
This time the hallucination didn't simply vanish in an instant. 101 found herself in a brand new (if distinctly purple-ish) science wing, complete with a whole bay of working terminals, and she was determined to use them to get to the bottom of this. Charon could only stand by as he watched her type away on the long broken equipment.
Wait, what? "You talk to me you stupid computer!!" 101 screamed then stormed back into the hall.
101 looked around, shaking. Charon, for the second time that day, put his hand on her shoulder and with great difficulty meekly suggested, "perhaps we should go." 101 nodded slowly, tears threatening. Was this another sick Vault-tec experiment that, perhaps, didn't affect Charon because he's a ghoul? Or was something unraveling inside her? The prospect was a frightening one. She began to feel a little better when they passed a corpse on their way out and 101 remembered that at least some of the Vault's residents had been driven to madness as well. The best course of action was, indeed, to get out as quickly as possible before whatever was going on had a chance to take permanent hold on her. Vault 106 was dangerous. 101 made sure to close the Vault door when they left and smashed the control panel. If Vault-tec did their job properly a person would need something stronger than a nuclear bomb to get 106 open again.
