* Heath apparently volunteered for the procedure that turned him into the ultimate network node within the networks of [[The First World]]. It wouldn't be too surprising if he was part of the infrastructure supporting [[Command]], as well as [[The First World]] shields, given his ability to readily connect with the systems. He is located in a reality somewhere near the [[Inner Shield]], possibly on a [[Branch World]]. His reality was visited by the children lead by [[Danny]], indicating it isn't one of the shielded (read-only) worlds previously discovered. One theory currently standing regarding Heath is that he may be related to the creation of the [[Inner Shield]] and [[Outer Shield]], which was built with the help of the [[Brownshirt]]s. He may even be a descended form of [[Brownshirt]] himself, which would explain why the [[Cordyceps Fungus]] infected [[Brownshirt]]s reacted as he adjusted the camera [[Cristina Thompson]] was using. Another possibility is that there may also be other 'Heath' level system administrators out there, performing similar functions.
* This has also been answered in 'Our Final Acts (Part 3)'. [[Heath]] is the last of eighteen human volunteers, who along with eighteen [[Brownshirt]] volunteers became the underlying infrastructure that creates and maintains the shields protecting human space in the multiverse.
=== What is on [[Cristina Thompson]]'s shoe? Why did the [[Regret Demon]] want it? ===
* Cristina's shoe contains dirt from one of the realities she has gone through in the past. How exactly Cristina traveled between realities is unknown, but she may have used various installations of [[The First World]], or through fractures in the realities similar to how [[Alek]] lead refugees towards [[The First World]]. What the dirt contained is unknown, it is unlikely to be [[GLORWOC]], as it would have spread and destroyed everything around it, so another possibility is another microorganism, such as [[Temporal Bacteria]], or a residue of some sort. Given the [[Regret Demon]]'s considerable abilities, it can be presumed that whatever was on the shoe is rare and hard to obtain, and provides a material advantage to the [[Regret Demon]], whatever its agendas may be.
* This has been answered as of 'Our Final Acts (Part 8)'. After the battle of [[Earth 44]], [[Cristina Thompson]] in despair activated the same [[Metallic Chip]] she had stolen as a teenager. Inadvertently she accessed the [[Orthogonal Reality]], an artificial reality separate to those of the standard multiverse realities. Her transport to and from this reality included a variety of materials, including the dirt on her shoes. The [[Regret Demon]] was able to analyse the shoe and dirt to determine the location of the [[Orthogonal Reality]], information which it subsequently traded to the [[Gemstone Hegemony]].
