On Forever Season 1 Episode 18, Adam returns. Watch Forever online now to find out what he wants and whether or not you think it could be possible.

When a deep sea diver turns up dead following an expedition which uncovered a chest of gold worth $7 million, Jo and Henry end up investigating the wealthy financier, Isaac Monroe, who bankrolled the expedition. Henry has a special interest in the ship the dead diver was excavating before he died because it was the ship Henry first died on in 1814. Isaac has a special interest in Jo. It's pretty much a win-win.

Hanson and Reece encourage Jo to go on a date with Isaac once his alibi for Rick Rasmussen's murder checks out. She agrees to meet him, tries to talk herself into leaving early, and exits the bathroom only to discover their date has been crashed by the actual murderer who has not set her sights on Isaac. Henry figures things out while Jo is on her date and he and Hanson race across town to warn her. She has already figured it out by the time they arrive.

Henry learns the real reason the Empress ended up 1,000 miles off course.
