As a teenager, Henry was popular both for his gift and for his magnetic personality. He was a goofy jokester, and he never backed down from a challenge. When authority didn't make sense, he was the first to stand up to it, and often the first to get reprimended.

He spent most of his time with Morgan and Prosper, his two best friends with a complicated romantic entanglement. They often got into trouble together, but Henry was often the one who took the brunt of the consequences that he'd warned them of. Henry began to close up like a clam due to this, and at the same time his reputation began to slip due to the amount of bad prophecies coming true.

After a particularly bad accident that scarred and incapacitated Henry, he went missing for around two decades. Most people assumed he'd died.
