Joan only needed to say those words for Harker to understand the full picture. He can see it vividly in his mind.
The people burned their house down. Victoria was at the patio, taking care of their father sitting in a wheelchair. He was already old, and the solution she had been using to keep his cells from dying was less effective because of this. Their mother was already in the state of catatonia that was similar to that of stroke victims.
People then arrived with fire and pitchforks, accusing them. Victoria just stood, addressing their concerns with logical excuses for their apparent 'inability to age'.
But as she did, a teenage boy had already sneaked around at the back and started a fire.
Joan was inside, so her legs were burned. She screamed for help…..
And Victoria went inside, leaving their parents behind as they were consumed by the fire. They escaped, and Victoria gave her a pair of new legs.
