Thor and Hildegarde return to Avengers Mansion, shaken by Sif’s willing disappearance. When Jarvis, the Avenger’s butler, attempts to serve Thor, the Thunder God lashes out, grabbing Jarvis and shouting, “I say thee– be silent mortal! I have no patience with thine endless, mindless prattling! If we do have need of thee, we shall summon thee but until that time doth come– begone!”
Hildegarde,who has always deferred to Thor in the past, lets him know what a shithead he is being. Thor sits and broods for a moment before falling asleep in his chair. When he wakes, he finds Jarvis and apologizes for his earlier bout of honesty.
Also, it turns out that Doctor Blake’s new landlord, Karl Sarron, was actually an alien being named Mercurio from the planet Gramos who was trying to harness the electromagnetic field of the Earth to save Gramos from an unexplainedly dire threat.
Apparently, every time Doctor Blake transforms into Thor or vice versa, the transformation discharges some exotic energy that lingers. Blake’s office is full of it. Mercurio used a Dimensional Oscillator to absorb that energy, transforming himself into a half-red, half-blue man with the power to create fire and ice. For no discernible reason, once in this new form Mercurio dubbed himself “the Fourth-Dimension Man.”
This form is a partial transformation into Mercurio’s true form, and apparently he decides that killing Thor is the simplest way to finish the transformation. The two battle and Thor kills his assailant, which has possibly doomed all of Gramos.
While Thor deals with all of that, Balder has struck out on his own, to try and deal with his feelings for Karnilla.
