This story is a sequel to The Mane Six Regret Playing Truth or Dare

Months ago, the Mane Six played their first round of Truth or Dare. As a result, they ended up having a rap battle, learned about secret crushes, and managed to start a beautiful relationship between one of the Mane Six and a Wonderbolt. Since their first game, Starlight Glimmer and Spike joined the fun. This week is the same as always. But little do they know, two unexpected guests come to play.
The rules are simple.
1. If choosing Truth, you must tell the truth when some pony asks you a question.
2. If choosing Dare, you must perform the dare some pony dares you to do.
3. You cannot change your choice once you have selected something to perform.
4. You cannot choose somepony to dare you to perform something or ask you something.
5. The game ends at midnight when Princess Celestia and Princess Luna say it ends.

It's recommended to read What Happens at the Lit Club... and The Mane Six Regret Playing Truth or Dare if you want to understand some stuff that's going on.

The ponies within Ponyville had enough trouble with the horrid onslaught of vines infecting, and spreading all over the place. What if, thanks to some off-screen shenanigans by a particular Draconequus, the vines didn't just spread to Ponyville, but also to the grand fountain of Rose Quartz! And what a time for that: the grand gems themselves need it the most. Just how much trouble will both worlds end up in, especially when one world is connected to another thanks to a force beyond them both? Will there be friends, foes, or both? Let's see where this ride will go. Many songs, adventure, and silliness to come!

Ponies and Gems unite!
