The chaos of time and space rules in Subspace had long exceeded the thinking limit of Murphy's dumb dog brain, but you couldn't really blame him; that kind of "super new human" who can use a human brain's computing power to derive coordinate mappings and spatial laws in Subspace probably hasn't been born yet.
According to Triss, only Subspace creatures with special thinking organs can, through instinctive inheritance, grope out the various ever-changing rules of this Chaos Domain; or, like the Sentinels, they're equipped with special hyperdimensional radars the moment they roll off the production line, to meet their needs for navigation and rapid movement when fighting in Subspace.
The only reason Murphy could precisely dive in to rescue Adel at the moment she followed him into Subspace was because of the Sentinel he was currently gripping in his other hand.
