Jenny does her best to follow her dad's voice, all the while continuing to try to work everything out, to ask, "But what happened? How did I end up stuck in my own mind?..." And in the instant that she finds them, that she "sees" her dad and Jack, everything clicks into place.
Instead of the darkness, Jenny is now reliving what happened with the Master. She doesn't move, she just stands there, overwhelmed as she takes it all in.
ooc: You guys can relive it all from Jenny's POV if you want, or not. I know all of this is in her mind, but I didn't want to godmod :)
