Harold hasn't gone through the portal. A part of him is curious about it, of course, a rather large part; but having no idea whatsoever about what he may find on the other side of it is a significant risk that he hasn't been willing to take. John's come back without a scratch, which is both a relief and a surprise, but that doesn't convince Harold it's a very good idea.

So he's been using his time to explore this Darrow instead, wandering on his own while John's preoccupied, sometimes with Bear and sometimes alone. Today, he'd come across a series of abandoned warehouses somewhat near the cemetery, and the portal is in sight but Harold actively chooses to ignore it. To ignore the temptation of what could be a better life or, alternatively, a far worse one.

When he spots John, Harold brightens, subtly raising a hand in return. "I'm well enough," he answers, which is true enough. "Any new stories from the other side?"
