The Val Jean was destroyed by ramming a Kazon  warship while fighting the Kazon-Ogla, and as a result the crew of the Val Jean, Henley included, joined the crew of the Voyager as provisional officer's in Starfleet during Voyagers historic trek home.

Being unfamiliar with Starfleet protocols, she had a hard time adjusting to life on Voyager. She and three other former Maquis, Kenneth Dalby, Chell, and Gerron, were selected by Commander Chakotay to participate in Lieutenant Tuvok's Starfleet Academy-style crash-course aimed at bringing former Maquis members unfamiliar with Starfleet up to date. On the first day of training Tuvok had her remove her "festive" headband, as it violated regulations. 

During a simulated battle exercise, Dalby ordered her to fire at will and do as much damage as possible to Romulan Warbirds attacking them. As a result, she, along with all the others, "died". Later, during one of the exercises, she, along with Tuvok and the rest of the team, rescued Gerron who was almost killed by a plasma leak. ()
