Season three
The third season opens with Max's quest to save his son. He and Liz are arrested in Utah after holding up a convenience store. They both end up getting out of jail, but their actions have serious consequences for the rest of the season. Max, during the holdup, found an alien ship that was being stored in the basement, but when he goes back, the ship is gone. While they are in a Utah jail, Michael searches for evidence Max tossed in a field while being chased. A man approaches him and warns him and the others to stop their search. This man is mysteriously murdered in L.A. by a fifth alien. Knowing that the alien is a shape shifter and in the film industry, Max tries out acting and auditions for a role in Star Trek: Enterprise. The fifth alien is, in fact, a very successful film producer who is also Max's protector. Max, against the fifth alien's wishes, forces him to help him find the ship, which is at a military base. They attempt to fly it but the ship is too damaged from the crash in 1947. Max leaves L.A. disappointed and he feels as though he has let down his son.
Isabel is revealed to be haunted by Alex's ghost, but it is actually a figure of her subconscious. She begins a relationship with Jesse Ramirez, an attorney who is several years older than her and works with her father. As the season unfolds, Max and Isabel's father is diving deeper into the past of his children, due to Max not giving him a satisfactory reason as to what happened in Utah, or why Max was even there in the first place. Midway through the season, Isabel gets married, much to the disappointment of her parents, Max and Michael. While on her honeymoon with Jesse, Isabel comes in contact with Kivar. He awakens Isabel's past self, Vilandra, who betrayed Max and Michael in their previous life for her love with Kivar, which is the reason the four of them died in their first life. Kivar tries to compel Isabel (now reawakened as Vilandra) to travel through a portal back to their home world, while Max and Michael attempt to stop them. In the end, Isabel pushes Kivar into the portal.
Michael and Maria are having trouble with their relationship, especially when Maria feels that the whole "alien thing" is ruining her life and decides to take a break from the gang so she can try to live out a "normal" life. Michael takes a job as a security guard during the night at a local pharmaceutical factory. But little does Michael know, the owner of the company has been going through the trash to obtain Michael's DNA, and the owners find out that he is an alien and kill one of Michael's co-workers "Munk" to see if he is "the healer" which is Max's power, so Munk dies. Michael and Sheriff Valenti find a room with all of Michael's things and realize what the company has found out; Valenti, however, is captured. Michael enlists the help of Max and Isabel in order to rescue Valenti. Max is taken and coerced into healing the dying millionaire. Max is, at first, wary of doing so, as the millionaire has lived out his life and will die of natural causes, but he tries anyway. Max ends up transferring his age, and the millionaire's body transforms into Max's body, killing Max. While Michael and Isabel try to come to grips with Max's death, a patrol of guards come. Michael and Isabel use their powers to destroy their vehicles, but Isabel is shot. The millionaire is at his house in Max's body when he receives a memory of Liz. He can't stop thinking about her, due to having Max's soul inside him, so he decides that he must kill her in order to get rid of Max. Michael inherits Max's powers after his death, which he then uses to heal Isabel. As the millionaire is about to kill Liz, they both fall from the 'Rat' (Rathskeller) window of Liz's boarding school. Seeing that Liz is about to die, Max takes control over the body and uses his powers to save her life while he hits the ground. The millionaire's soul dies and Max miraculously survives after Liz kisses him. The group heads back to Roswell.
The FBI has been studying the group for many months and is closing in on them. Liz begins to exhibit alien powers, including premonitions, towards the end of the season, which later causes her to become a target. When Tess returns with Max's son, Zan, the gang has to group together and try to escape Roswell. Tess' arrival causes the FBI to find more evidence of the aliens, including a video revealing Isabel's powers. Everyone is angry with Tess and at first tries to kill her, but instead end up helping her. Because of Liz's forgiveness, Tess decides to sacrifice herself by turning herself in and blows up the military base. The baby is revealed to be fully human, as only Max's and Tess' human DNA produced the baby. Max, realizing that the baby can have a normal life, gives him up for adoption. He uses his father's help to get the baby into a good family.
The series closes with Liz getting a premonition of her, Max, Michael and Isabel dying in an FBI setup, so they decide to leave Roswell after their high school graduation. With the realization that he will be leaving possibly forever, Michael professes his love for Maria and she makes the decision to be with him no matter what. After Liz, Max, Michael, Isabel, Maria and Kyle escape from their high school graduation, where the FBI setup is, they hit the road in a bus, where there are several emotional goodbyes, especially between Kyle and his father, Jim Valenti. Isabel decides to leave her husband behind in order to save his life. The final scenes of the show feature Max and Liz getting married and Liz's father reading Liz's journal, chronicling the last three years.
