The Crossed series isn't a big one for continuity. Something happened, people are turning into monstrosities of humanity and destroying each other in increasingly hurtful and disgusting fashions, exhibiting the sickest type of humour when doing so.
But you don't see people from one Crossed series appearing in another. Their stories are separate, often by geography.
This is the final page of last week's Crossed: Badlands #12. Those familiar with the series may have had quite a surprise. Others will have just had a mysterious cliffhanger.
Here is that last page. The top two thirds of it at least, there's even more spoilers on the bottom third.
That's Harold. Harold from Crossed: Psychopath, also by writer David Lapham.
