Proctor and the Gatherers continued to build their presence on Earth-616 over the weeks that followed. Magdalene's counterpart was discovered (the non-superhuman Marissa Darrow), and she and Proctor gathered the unsuspecting victim. Black Knight and Hercules were nearby for the 
event, and gained a small clue about the Gatherer's true nature from Darrow's disappearance. [Avengers (1st series) #348] The Gatherers used their cloaking effect to enter the mansion again, sabotaging one of the Avengers’ air-skimmers. [Avengers (1st series) #349]
Meanwhile, Proctor began his own manipulations outside the awareness of his minions. Through the Gann Josin, he started influencing the mind of Sersi-616. This Sersi had only been an Avenger for a few months, having spent the previous few millennia as a hedonist and, most recently, a New York socialite. Her turn towards super-heroics was already considered whimsical and out-of-character to some. Proctor had an added benefit to his schemes, for Sersi had recently joined with the Brethren in a Uni-Mind. The Uni-Mind was a physical and mental composite state the Eternals achieved to make collective decisions for their race and share the psychological burden of eternal life. However, superstitious warnings existed among the Eternals about the taboo of joining with an alien Uni-Mind, as Sersi did with their Brethren cousins. As Proctor began prodding Sersi's subconscious, giving her mood swings and a more aggressive temperament, she feared the Brethren merger was the cause and didn't suspect his outside influence.
On another gather, Proctor's team found a surviving Avenger named Coal Tiger and prepared him to join their band. They braved Avengers Mansion a third time to access the team's files and identify Coal Tiger's 616-counterpart, the Black Panther. The Gatherers got too cocky, however, for the Avengers had become wise to their infiltrations. Black Knight engineered the tech needed to counter their cloaking effect, and the Avengers caught the Gatherers in their home. The Gatherers managed to escape and traveled to Wakanda for Coal Tiger's gathering. The Tiger had not yet been exposed 
to Proctor's influence, though, and he refused the dishonor of claiming another's life to save his own. Coal Tiger's words also strongly impacted Swordsman as well, who began to see through the fog Proctor cast on his memories and recognized these Avengers were not the ones who he thought abandoned him. Coal Tiger chose to die rather than let Black Panther be gathered onto him, and a hesitant Swordsman was caught by the Avengers before he could escape with the other Gatherers through Magdalene's slashway portal. [Avengers (1st series) #355-356]
Magdalene begged Proctor to rescue Philip from his captors, and Proctor intended to respond... in his own way. He thawed out Tabula, a shape-changing synthezoid who previously served on the Gatherers, and had the Gatherers retrieve a malevolent incarnation of Vision from another collapsing reality. [Avengers (1st series) #358-359] Proctor arranged for Tabula to lure the Avengers' Vision into an ambush, capturing the local synthezoid. He then brought Vision and "Anti-Vision" together and, instead of gathering them, Proctor swapped their core consciousnesses. Anti-Vision was therefore primed to access Avengers Mansion as a spy, posing as his heroic counterpart. While Proctor assured Magdalene that Anti-Vision was there to rescue Swordsman, the jealous Gann Josin actually ordered his new henchman to murder Philip when the opportunity arose. [Avengers (1st series) #360]
Anti-Vision's covert insertion into Avengers Mansion was made easier by Sersi, who began a rampage lashing out at her fellow Avengers. Proctor's influence had made her increasingly erratic and brutal in combat. When the religious zealot Anskar killed a child in her care on Polemachus to appease his gods, Sersi avenged her by disintegrating the man. As the Avengers considered whether to begin a formal reprimand for violating their by-laws, the other Eternals arrived as they sensed Sersi's distress. It was Ikaris and the others who suggested the Mahd W'yry had taken Sersi following the Brethren incident, just as Proctor expected.
The Gann Josin was brought up as a palliative for Sersi's condition, but circumstances on Earth-616 were quite different than they were on Proctor's Earth-374. Here Dane Whitman was in love with the Inhuman Crystal, but they could not act upon their feelings as she tried to repair her marriage to Quicksilver. The Black Knight and Sersi had begun a tryst as a distraction on Dane's 
part, but Sersi had come to truly care for him. Here then, instead of a bonding ritual signifying a lifelong commitment between soulmates, the Gann Josin was thrust upon Dane Whitman by the Eternals in the hopes that his stable thought patterns could calm Sersi's mood swings and keep her from going insane. The Black Knight was forced into this mental responsibility for Sersi without being given a choice in the matter. [Avengers (1st series) #361]
As the Avengers reeled from these events, Anti-Vision made his move and attacked Swordsman 
before attempting to force himself on Crystal. He was captured, and made to lead the Avengers to Proctor and the Gatherers' base in the Andes Mountains. [Avengers (1st series) #362] A surprise attack allowed the Avengers to gain entry and rouse the Gatherers from their abode. Proctor emerged and confronted his foes in this reality for the first time. He ripped the prisoner Anti-Vision in twain for failing him, and went on a jealous tirade after seeing this world's Black Knight had undergone the Gann Josin with Sersi. Proctor's possessive ranting even left the Avengers confused over whether Proctor was claiming to be the husband of their Sersi, given how furious he became. He even prodded Dane Whitman through the Gann Josin into giving in to rage and attacking Captain America for his amusement.
Composing himself while the Avengers separated their quarreling members, Proctor fell back into his assumed role of prophet of doom. He claimed Sersi's growing madness was responsible for Dane's outburst, thanks to the Gann Josin. Proctor laid out how the Gatherers' mission was to prevent this world from falling to 
Sersi's insanity as with each of theirs before it. Proctor even dramatically revealed Ute, or He-Who-Dreams, in an effort to awe and distract the Avengers into taking his word that Sersi was the threat. This display drew the attention of Uatu, Earth-616's local Watcher, although his vow not to interfere prevented him even from rescuing his fellow Watcher from this ill fate. Knowing Uatu would remain silent, Proctor pontificated his version of events before the Avengers, daring the Watcher to contradict him.
