Sprx was cocky, insanely loyal, devoted, and he was full of love.
They may have argued, but Gibson was glad to have him by his side. His flirting got annoying where even Nova hit him multiple times without fail, he was too cocky for his own good and he acted like he was better than everyone else. Yet he was loyal, willing to sacrifice himself for the people that he loved. Even if Gibson wanted to kill him at times, he couldn't truly get rid of him nor could he trade him for anything else in the universe.
There were no red or pink flowers that could describe everything that Sprx was to Gibson. None of it could describe his feelings perfectly. It didn't matter what he combined, it was never the result he desired.
So he looked outside of Sprx's color to find something. Lavenders were the only thing that came to mind for Gibson. Sprx was in no way serene, but a few of lavender's meanings fit him perfectly. They were also perfect in terms of colors, as red and blue created purple. It wasn't too out of what Gibson went for when he gave everyone flowers. Lavenders just happened to be different in a perfect and fitting way.
Unlike everyone else, Sprx never got the whole symbolism thing down. Every time Sprx gave him a flower, it never said how he felt and what he thought. Gibson had argued him down on the importance of the flowers' meanings, yet in the end only a little bit of that information stuck in Sprx's mind.
Gibson gave him the lavenders upfront. He didn't leave them at his bedroom door or put them in his room. He gave them to him in person. For a split moment, he could see the surprise on Sprx's face before he grabbed them and smiled.
Meanings: Grace, devotion, loyalty, and love.
