Palpatine's birthday cake, and what went wrong

A quick (fan-fiction) outline on why Amidala, Qui-Gon, and Obi-Wan are disliked by Palpatine. These events take place prior to Episode I.

• Palpatine has money and tells Amidala he wants a birthday cake specific to his vision.

• Qui-Gon gives Obi-Wan Kenobi the decorations for the cake.
• Obi-Wan works on the decorations. Qui-Gon bakes the cake.

• Obi-Wan turns decorations in to Qui-Gon.
• Qui-Gon approves.
• Qui-Gon turns in birthday cake to Amidala.
• Amidala thinks cake looks great.
• Amidala turns in cake to Palpatine.

Where did it go wrong?

Obi-Wan only worked on the decorations Qui-Gon gave him. Turns out Qui-Gon knew about a lot more decorations that were created by a missing Jedi Master named Sifo-Dyas, who was an expert on Palpatine's cake. Obi-Wan assumed that the decorations he was given were complete. Qui-Gon did not notice anything was missing. Obi-Wan should not have assumed everything was complete or filled in the missing decorations. Sifo-Dyas, the expert in the project, was never around to review Qui-Gon and Obi-Wan's work. Qui-Gon and Obi-Wan should've made sure everything is complete by tracking down Sifo-Dyas. And now Palpatine will bad-mouth Amidala, Qui-Gon, and Obi-Wan to the Galactic Senate and the Jedi Council, lowering Qui-Gon and Obi-Wan's potential for baking future cakes.
