The one in Headquarters stays there, and a new Sue appears in the 'fic.
I'm basing this off of a system a friend of mine developed for a ttRPG that had heavy time travel elements. There existed areas not fully cotemporal with any other timeline (much like Headquarters) that would not be affected if history was altered, which we called causally protected zones. A person (or any object, really) could enter the CP-zone from their timeline, have that timeline changed so that they never got that far, and then exit the zone to exist alongside the other version, a process we called causal orphaning since it created objects with no apparent origin point. From the altered timeline's perspective, CP-zones became essentially a source from which things that might have been, but did not, would occasionally manifest.
