Page 3 of my first ever comic. Seems whatever was in that patch extended Vexx's climactic response to some sorta mind-melting extreme. That diabolical clone was just in it for itself from the very beginning!
Flashing forward a bit, we thankfully see that Vexx managed to get out of his sticky little situation with his own original identity, safe and sound. Alas, he clearly did not manage to survive the scheming of his clone unscathed.
Yes, indeed, Vexx most certainly had a much greater libido to wrestle with than ever before... and it was very likely it would never settle back down again. Teasing brats, be warned!
