Will Mason was a Communications Officer in the Combat Information Center (CIC) aboard the USS Nathan James. His rank in Season 1 was Ensign (O-1), which means he was recently commissioned.
Mason was shown to be hesitant in his duties, specially when questioned about what he saw or heard on the CIC equipment. However, he stands by his impressions and admits when he is unsure. He is one of the crew members assigned to listen to distress calls from around the world in an attempt to get news about any of the crew's loved ones.
He was also a key member in detecting things on radar, most noticeably with tracking the Immunes' submarine.
In the premiere episode of Season 3, he was captured in Vietnam by pirates along with 6 other members of the Nathan James. During the ambush at a night club, he was shot in the torso. In S3E2, "Rising Sun", he is shown to be bleeding profusely. Doc Rios begs their captors to give him some medical equipment so he can treat him, but the captors grab Mason instead and drag him off to an unknown location. At the end of the episode, it shows Mason on a table being drained of his blood (for unknown reasons at the time). It can be presumed based off of the amount of blood he had already lost (from the bullet wound) and his declining condition before they drained his blood, that they killed him.
In the series finale, LTJG Mason is one of the characters with whom Tom had served (most of them deceased,) who appears in his hallucination as he is drowning, after Nathan James sinks ramming Gustavo's Battleship in order to end the war with Gran Colombia. Tom views, and then is part of, an award ceremony for him, which also serves as a change of command ceremony for Nathan James. When President Michener asks Tom if he is ready to be relieved (as commanding officer,) Tom hesitates and wonders aloud who he is passing responsibility onto. Will is one of the sailors in the audience for the ceremony (who are also Tom's close friends and allies,) stand and declare that they have the watch, allowing Tom to finally achieve peace and be able to mentally and emotionally let go of both Nathan James, and of the burdens he has carried around since the plague began, secure in the knowledge that others will always be there.
Ultimately, Tom decides to keep fighting, swim to the surface, and live.
