I have no idea if what they say is true, or just another bit of bile. Either way, I'm done listening.
When Twilight exited the glowing door, she found herself in a room full of mirrors. There were no visible doors, windows, or passages out of the room, just mirrors of every shape and sized stashed in every corner.
"Let me guess, you here to escape right?" Twilight turned to try and find who had spoken. She looked around, only ever seeing a piece of reflection.
"Show yourself!" Twilight demanded. "Very well." The voice called. Twilight looked around, finally seeing an unmoving reflection. She turned to look at the owner of the reflection, but there was none. Confused, Twilight turned back to the mirror. The reflection chuckled, and stepped out of the mirror, "I do so enjoy it when they make it this far." The figure seemed to be a living mirror case. Twilight assumed that this was the 'Mirror Man' that she'd heard about during her information gathering. The words, 'Heaven, Hell, True, False,' were written along the edges of the box; no eyes or mouth visible.
"If you're going to try and stop me, I will fight." Twilight said, igniting her horn. Mirror Man laughed, "Oh that's adorable! No, I won't try to stop you, but I also see no need to help you." Twilight remembered that she'd seen no exits.
"How do I get out of here?" Twilight questioned. "Why, only the truth shall be your escape, but I don't think you want to see it." Mirror Man told her. "Show me." Twilight demanded, unsure of what exactly she was asking, but not caring so long as it helped her escape. "Are you sure? You might not like what you see." Mirror Man cautioned.
"Show me!" Twilight shouted, firing a warning shot of magic energy less than a few inches away from Mirror Man. Mirror Man chuckled. "Very well, but I warned you."
Mirror Man swung open the doors of his mirror box body, reveal Twilight's reflection. Then slowly, the image began to change. The mirror revealed a tall alicorn. After a moment, Twilight recognized princess Celestia. Princess Luna entered the view. "I know that you are distressed sister, but there was nothing that you could do," Luna said, "There is a silver lining to this. Now that old fear of your's will never come to pass."
"What fear?" Twilight asked quietly. As if in answer, the image changed, revealing a picture of Cadence and Twilight herself standing in front of a wall. The image itself looked peaceful, but then the shadows cast by the two alicorns spread up the wall. Cadence's shadow took the shape of a battered, weakened alicorn begging for mercy; Twilight's morphed into the alicorn striking Cadence down.
"At least now," Celestia's voice said, "History will not repeat itself."
Twilight stared at the image, horrified. They don't think… they don't believe that I would ever… It was too much. Twilight, in spite of herself, began to cry. Then the gypsy's words replayed in her head. Crying. Yes, I see crying in both the near and distant future. If you wish not to be defeated, I suggest you dry your tears.
Twilight was done crying. She looked at the now laughing Mirror Man. "I told you that you might not like what you would see, but you didn't list-" He was cut off by Twilight firing a blast of magic, hitting him directly and sending mirror shards in all directions. Mirror Man flew back, and Twilight began firing her blast aimlessly through the room, destroying the mirrors.
Eventually her attack revealed a tunnel behind a wall sized mirror, which she promptly ran through. She didn't plan on letting anything else stop her. So she didn't slow, even when she heard the yelling.
"Intruder alert! Intruder alert! Intruder alert!"
