Learn some basic programming, duder.
"null" as envisioned by higher-level languages like Java or C# is in some respects a quarantined alias for zero. And the way you know this is by looking at how zero is used in many similar contexts in languages like C and C++, especially when referring to memory addresses.
EDIT: Also, if one of the JCM nulls ate the other, the survivor would finally be an acceptable mate, not for Chantal, but for Peetz, absolutely.
