Sunstone is a natural pacifist, whereas Moonstone is always willing to fight for what she feels the need to defend- in most cases, Moonstone will draw her sword, getting Sunstone involved in battles he doesn’t necessarily want to be fighting in. Furthermore, he doesn’t even feel equipped to fight, since his weapon is a shield. Ultimately, he finds himself wrapped up in the battle and trying to provide coverage for Moonstone while she wrecks shop. In deadly situations, they’ll form Orthoclase so there’s only one body to keep track of.
