J’onn must return to Mars, and he thinks that M’Gann is in danger. However, the truth is that his father, thought dead for hundreds of years, has been found as the last prisoner of the White Martians. He is the only one who knows where the White Martians are moving a scepter that could potentially wipe out the resistance without even touching them. J’onn must figure out how to convince his father to tell them where they are moving it, but his father is convinced that his son is dead.
Maggie and Alex are having their wedding bridal shower, Maggie decides to invite her father, whom she hasn’t spoken to since he kicked her out of the house when she was 14 years old. He arrives and seems to be making an effort to change and accept his daughter. However, in the end, he cannot accept that she is choosing to be an outcast by marrying a woman, when he worked so hard to make her not be an outcast because of their race.
My favorite parts in this episode were J’onn finally being able to reminisce about his family with his father and Maggie getting closure with her father and realizing that he is just not going to be able to accept her. Both of these things were important in the development of the characters, as J’onn is finally getting closure about Mars, and Maggie about her life in general. I am also glad that I am getting to see the side characters get a lot of screen time this season!
