She didn't personally think it was something Billy needed to apologize for- coming to this universe was the best thing that ever happened to her- but she guessed it made sense he would feel bad about disrupting everyone's lives and uprooting them to this place.

She crossed her arms and watched Kate, waiting to see what she was going to do now.
