Character Description

Snake Codec

 * (Mei-Ling) Snake, have you ever heard "It takes two men to make one brother"?
 * (Snake) You know I'm not the right person to talk to when it comes to brothers.
 * (Mei-Ling) Oh, right. Sorry. Well Billy and Jimmy Lee are at their best when fighting together. They've collectively known as the Double Dragons and when they fight alongside each other, there's next to nothing that can stop them.
 * (Snake) They do seem pretty close as far as brothers go. I'm starting to envy them.
 * (Mei-Ling) Well even they have their disagreements. They fought each other because they loved the same woman, but when she died sometime later, they pulled together to support each other.
 * (Snake) I can't say the same for any actual "brothers" I have, bit I've at least known feelings like that before.
