Isaac sighs and says, "I can only say that I'm glad you didn't." After a few moments, he rests his head against Hayley's and, taking her hand in his free one, says, "You know, I'm glad things seem to be getting back to normal already. Sarah would want us to move on." Then, a few more moments pass until he adds, "And I know she wouldn't want us to get revenge...but I'm not gonna stop until all the members of Crey are dead at my feet."
