- "Your mother was brave, just as your father was foolish. Which are you? So you take after your mother, huh? Or not."
- —Vandal Savage to Jonas[src]
In 2166, Jonas and Miranda witnessed Vandal Savage's attack on their home. Jonas watched helplessly as his mother was killed by Savage's men. Savage asked for the boy's name and taunted how his mother's courage was only rivaled by his father's foolishness. Savage mockingly wondered which quality Jonas had. In response, Jonas defiantly spat in Savage's face and was promptly shot dead.
The deaths of Jonas and Miranda were the catalyst for Rip to time travel back to 2016 and recruit 8 men and women who had a minimal effect on the timeline to help defeat Vandal Savage once and for all.
