"Supergirl" season 2 has had everyone's spirits lifted up, and many questions are on fan's minds, including a very important one being what is Mon-El's secret? A vague answer would be that he is more important to his native planet Daxam than earlier thought. Mon-El's secret in Supergirl season 2 might be linked to his hidden past.
In one of the sneak-peeks in "Supergirl" season 2, Mon-El made it clear that he should be the first one to investigate an alien spacecraft, should it arrives. As a consequence of this choice, he gets the help of the DEO to beam him up to the spacecraft.
Kara, however, unexpected to him, willingly decides to follow. Kara only did it out of her care for him, to Mon-El's surprise and dismay. However, Kara is surprised to find the occupants of the ship bowing before Mon-El and asks Mon-El what is happening. According to some "Supergirl" season 2 rumors about Mon-El, he might be the prince of Daxam.
It might be possible that Mon-El being in the alien ship might avert the crisis, and that his parents (played by Teri Hatcher and Kevin Sorbo) are only there to take him back to Daxam. According to fans, Mon-El's parents are royalty of Daxam.Given Daxam's enmity with Krypton, it remains to be seen how the relationships between Mon-El and his parents would unfold, since Mon-El is with Kara now, who is from Krypton.
According to "Supergirl" season 2 rumors, fans are speculating that Mon-El might be presented with an interesting choice, either to leave Kara and Earth or stay there and fight against his parents. Most theories point to the fact that Hatcher might be one of the Big Bads in this season. Whatever happens, all will be decided upon Mon-El's reaction and reply.
Stay tuned for more "Supergirl" season 2 rumors and updates.
