Opportunities
From his vantage point on the rooftops of Traverse Town, he watches Xion as she speaks with Riku. The light to his darkness, the original replica—no. i. The one who was accepted as the fourteenth of the thirteen when he was left behind—never given the opportunities she was.
He never really got to know her before, but he's spoken to her a little in the time since she awakened in the world of dreams. Even then, he should've known he never had a chance.
After all, he's just Riku's replica, a pale imitation of the Real Thing she clearly loves.
Author: Because I'm actually fond of Repliku a bit, too... And feel pretty sorry for him overall. (I mean, if Namine got the short end of the stick... I'm pretty sure Repliku was beaten over the head with it until he broke.^^;)
I was actually stumped on the prompt "opportunities" until I remembered him. x3 They're never shown to have met, but since they were both Replicas it's likely they knew of each other, at least. Also, unless I'm mistaken Repliku is shown in the trailer for 3D (and Xion clearly was) so it's definietly possible that they might meet up in the world of sleep. That interaction has found it's way into my head-canon now, in part because of the layers it adds to the situation.
But poor Repliku... He loves Namine thanks to the planted memories he was given, but has some feelings for Xion, too... But knows she loves the REAL Riku, not him. In fact, he knows Xion has most likely only turned to him for support because he looks like Riku. :/ Tough luck for him...
