 Even when Gray states that he will never forgive Jack for losing him, Jack, refusing to give up hope on his brother, simply chloroforms him rather than killing him, leaving him in cryopreservation in the hope of someday being able to help him.Even characters outside the main cast demonstrate the ability to redeem themselves; the earliest example is Tommy Brockless, a WW1 soldier suffering from shell shock and destined to be executed for cowardice, who sacrifices his life in his present to willingly spend nearly a century in cryosleep to await the day when he will save the world in the future, overcoming his fear at the last minute, thanks to his love for Toshiko.Beth Halloran, a young woman whose fiance is apparently killed in an alien attack, is revealed to be a member of Cell 114, a group of alien sleeper agents who program themselves with the identities of the races they invade to learn their secrets, but Beth nevertheless overcomes her programming in order to help the team defeat her 'comrades' in the invasion, subsequently forcing the team to shoot her to prevent her possibly endangering them in the future.
