Grammar note: the possessive form of “Light Sparks” is “Light Sparks’s,” since his name is a singular noun.
That’s debatable: a trailing apostrophe is almost universally used on some subset of names ending in “s” (Moses’, Jesus’, Socrates’, etc.), and some style manuals extend this rule to all such names.
