The collective unconscious of humanity was... rattled to say the least. When an being claiming to be an alternate and more successful version of it appeared and started insulting them, Alaya was tempted to throw him back where he belongs... until he pulled them into a humanoid form and started beating its new body with a baseball bat.
She tried summoning their loyal playthings- *ehem* honorable guardians, and undo him, but he started ranting about the counterfeit throne that a certain 'spider' made.
He made it very clear that that... 'thing' was still in that throne and could be summoned anytime and anywhere as long as it stayed there. Worse still, since multiple copies of the same servants could exist at the same time, one holy grail war could produce seven of these... counterfeit grand foreigners, who at that point could probably reverse engineer the summoning system and summon more and more.... effectively creating infinite grand foreigners that could just dogpile every opposition- not that they needed to.
At that point Alaya panicked. This was a major threat, and who knows how often this had already happened? And why didnt they remember something like this happening?!
The figure answered that he suppressed its memories to make this conversation more interesting. She made an apparition of Solomon fire a Ars Almadel Salomonis at him.
Being the unconscious of humanity, they were every human all at once, so it could just do this. Spamming beams was great, they mused.
No effect. He blasted the apparition with dark energy, then told her that as long as humanity was alive in any shape or form, this wouldnt work.
He then offered his job at a pesthunter, claiming he was an expert at removing crystal spiders from the ceiling. They asked what he wanted for it, being quite desperate at this point.
"Your job".
After ten more beams fired at him, and a few hundred hits with a broom on their head they decided to accept this, on the condition that if he failed he would leave. The thing readily agreed.
This was a really bad day for Alaya. It decided to make an offer to a therapist, but only for them. Its lovely dogs didnt need it. All they needed was them.
