Episode 18 of "Forever" showed Henry, Jo and the team deep-sea diving and salvaging through a sunken ship, according to Entertainment Weekly.

More of Henry's past is learned in Episode 18. On the night that he was shot and "killed," he was trying to free 300 slaves. He was killed before he could give them the key.

The gun that was used to kill Henry is smuggled out of the Explorer's Club by Adam and sent to Henry at the lab.

Also, Jo meets Isaac Monroe and the two start to take a liking to each other. They agree to go on a date.

While on their date at Isaac's apartment, an intruder breaks in. Jo is equipped with her gun and is able to defend herself from the intruder. Even though Jo told Isaac she did not have her gun with her, she in fact did. Still, Isaac says there will be a second date.

The 19th episode of the first season of "Forever" will give the team their first cold case, according to SpoilersGuide.

Jo and Isaac go on their second date. The two decide to go to a punk rock club. Someone at the club finds a mummified body of a woman in a wall at the club. This becomes the team's first cold case.

The woman has been dead since the early '80s and may have suffered a drug overdose.

Punk rocker Eddie Warsaw was her boyfriend at the time. He was convicted of killing her 30 years ago, but has maintained his innocence.

Henry feels for Eddie, as he has lost Abigail, the love of his life. Henry gets emotional thinking back to 1984 when she could no longer handle the age difference between the two. Abigail tells him she is taking some time away, but never returns.

The episode is titled "Punk is Dead" and it will air next Tuesday at 10 p.m. EST on the ABC network.
