Liz Stroller

Elizabeth "Liz" Stroller (Kathy Roberts) was a time traveler from 2015.

Before the Event
Liz was the mother of Kurtis Stroller and stepmother to Emma. She is divorced, and Kurtis becomes a trouble child, increasingly disrespectful and drinking. She was also a part of the Zion diabetes "cure" research, chosen because Emma was a lab technician there.

Season One
In 2015, she fell asleep, and woke up in 2012 with Kurtis now 13 years old. She dodged her past self, Lizzy, and stayed in a hotel. Later, she broke into her own home and researched what happened to her and accidentally answered the phone, with Kurtis on the other line. From her research, she called time travel expert Dr. Alexandra Gellar to ask questions. She then spoke to stepdaughter Emma to ask questions about Zion's diabetes research. Finally, Liz met with Lizzy and Kurtis and told them everything. Later, in her dreams, she met the other time travelers in the Dream World and learned she is not alone.

Season Two
Liz and Lizzy balanced custody of Kurtis, but she later caught her son sneaking out of the house and forced him to go back and confess to his mother. Months later, Liz was approached by a woman named Hillary Cole, who claimed to be a former employee of Zion who needed her help. Hillary explained that, in the original timeline, she had worked at Zion, and in the next timeline, she had been Gellar. She also explained that she had jumped again, and that all the others had been killed off and assigned Liz to look into a woman named Meryl Woolsley, who may be involved.

Season Three
Liz reported to Hillary her doubts that Meryl was involved in the deaths, and also reported that fellow time traveler Adam Reese has been killed. She later went through Hillary's things and found a list containing names of girls killed since June 2012. When she confronted Hillary about the list, Hillary confessed that she was, in fact, Samantha Stokes, born in 2004. Having been given the same diabetes shot, she has lived through the event on August 29, 2015 multiple times and taken many aliases, killing her past versions each time she'd done it. Disgusted, Liz stormed away.
