Bell's Links
"Helios, for the love of ANYTHING, can you annoy someone else instead?"
Bell is tired of him 100% but, Helios is valuable to her, someone they'd even call a friend. Sometimes Helios would show up all battered or maybe she'd find him pretty much on the brink of death to which Bell curses him, and patches the grunt as best as she can just to still keep him around.
Helios sees Bell as a sister, it's the sole reason why he acts so goofy and carefree around her. "I can kill you," can threaten Bell at him and Helios will laugh, he knows she won't, they're too important for that :)
He's also very grateful for the many times Bell's managed to heal him back to 100%
