"Don't forget me even if another Cait Sith comes along."

Those were the last words Cait Sith said to Cloud and the others before making the sacrifice of retrieving the Black Materia and getting crushed by the temple of the ancients in the process afterwards. And even though a new Cait Sith did show up to rejoin the party you still didn't forget what the original Cait Sith said.

After saving the world from Sephiroth with Cloud and the others you all would celebrate at the Golden Saucer, well celebrate wasn't really what happened. While you all were glad you saved the world, that didn't change the fact that people you guys cared about ended up dying in the process, Jesse, Biggs, Widge, Aeris/Aerith and Cait Sith....... All of them passed on in the attempt to save the world. They'd never be forgotten..... You would sit at a table watching Cait Sith #2 dancing on stage as you would just sigh. And while you didn't tell the others this but you felt bad for Cait Sith when the party shunned him for his "betrayal" especially since he didn't betray the party as he was being controlled by Reeve (Who would redeem himself later on), you made yourself a promise to always go to the crater to thank the original Cait Sith for his sacrifice.

You would then get up and head out of the Golden Saucer as you eventually made your way to the Crater looking down from above as you just sit there wondering what you could do in return you decide to climb down into the crater as you started digging. You didn't know why but you felt a sudden urge to dig through the crater. As you were digging you would toss aside rubble and other debris as you would be digging around for hours until eventually you would find some metal. And as you pulled out the metal piece you realize this might be part of Cait Sith. as you looked at the piece of metal you realized what you could do to thank him. soon hours would pass and you would have found some more pieces of metal although not really much, but it's not going to stop you as you would grab the pieces before heading home and calling it a day.

soon tomorrow would come and you would of course head back to the Crater to continue digging hoping to find more wires or metal. Days would turn into weeks as you would find some more pieces as you decide to go find some more scraps of metal and wires and other components at the ruins of Midgar you haven't been there in a long while as it has since been abandoned. you would head to one sector to start your search there, and when you think you found everything you could use then you'd go into the next section. That would take around five months, but you eventually found everything you needed as you started rebuilding Cait Sith.

A month would go by, then another, then another, and then on Christmas Day you were finally done you had completely rebuilt the original Cait Sith one that could do anything you ask of him, with his own sentience and he wouldn't be controlled like before. You also borrowed Cait Sith #2 and shared his memories with Cait Sith so he'd know who you were and who Cloud and the others were as you pick Cait Sith's body and carry him to your room as you lay him on your bed before leaving the room as you didn't want to freak him out as soon as he woke back up.
