Though there's no direct answer, Lemon's music let him muse over the past. A song he heard long ago, one popularized on what was another planet at the time, one that always inspired him and reminded him of the wonderous he had with this mysterious C-2.
Running about hallways of white petals floors, slamming against walls some substance called 'cellulose' solid enough to withstand almost anything, baring clothing made from spun vines, going through doors of large leafs, always treated patients or subjects in some sort of lab. C-2... Feral at times, a troublemaker who loved to run about and yell, but even so- his energy was contagious.
He often talked about a place dubbed 'Planet 83', and claimed they both came from there. Though the memories elsewhere were fuzzy, as Lemon's little 'mental animatic' stayed upon the song's visualization, he would always vividly remember C-2.
...Even now, even after being blown off-world.
