Samantha was not home at that time and neither was Bill, so they couldn't save Sarah and she died a brutal death.
This was why Samantha entered the world of assassins, she wanted to avenge her mother's death.
After David informed Chance of everything, he felt bad for what Samantha and Bill went through.
He lost his parents once, but Samantha lost her parents twice.
Because of this incident she and Bill stayed away from each other like strangers and not together like a family which was a brutal fate for her.
After knowing what happened with Samantha and how unfair Excalibur was for harming an innocent person for his revenge, Chance decided to use his adopted father's name to bring Excalibur out of his hiding and to get him killed by Bill and Samantha.
"Fine, we will use uncle's name to get Excalibur out of his hiding and will give his details to Danger-Ace and The Exterminator." Chance declared and David hugged him happily.
