"Legends of Tomorrow" Season 2 will determine if Professor Martin Stein will keep his personal aberration alive. "The Flash" Season 3 Episode 8 revealed that the woman in Stein's visions is his daughter.
In "The Flash" Season 3, "Arrow" and "Legends of Tomorrow" Season 2 crossover, viewers finally learned the identity of the woman in Stein's visions. He finally met the woman, who turned out to be the aberration he created when he interfered with his younger self in 1987. The woman greeted him when he arrived back in 2016.
To recap, in "Legends of Tomorrow" Season 2 Episode 6, Stein saw images of a woman whom he did not recognize. However, he told Jackson that he is sure he loves her.
Apparently, this woman turned out to be his daughter named Lily. Stein arrived back on 2016 Earth 1 to a surprise that greeted him at his home. Just when he was about to get inside his house, the woman opened the door, hugged him and called him "Dad."
Of course, the professor was caught by surprise, but he immediately recognized her face. Nevertheless, Stein left his daughter standing at the doorstep, when he immediately excused himself and left.
The question now though is, will Professor Stein let this aberration live in "Legends of Tomorrow" Season 2? Now that he knows she is his daughter, there is a likely chance that he may keep it that way. After all, he and his wife Clarissa never had a child to begin with.
Likewise, it appears that Lily will be staying on 2016 Earth 1 after all. According to Cinema Blend, "Legends of Tomorrow" Season 2 has cast actress Christina Brucato for a recurring role as Lily. Viewers should expect to see her appear in several more episodes in the series. This could only mean that Martin Stein eventually decides to keep his daughter.
