(OOC: Aww. Yeah, it's kind of sad because he thought she'd just up and vanished on him. Something that happens in their last adventure makes it so he doesn't remember it at all and all he remembers is finding a note Charley had written before she'd changed her mind saying that she was leaving. And she's nowhere to be found because she's stuck in the year 500,001.)
[Except that she already knows where the TARDIS is and she takes her own shortcuts until she's almost caught up to him and sees him slipping inside. She catches up and starts knocking on the doors.] Please. I just...I just wanted to say goodbye properly.
[Tears well up in her eyes and she turns around, using the doors for support as she slides down them.] I don't even know why you didn't come back. I told myself you'd died. That when the TARDIS disappeared, it didn't just leave, it was eaten. That's why I was coming back. To warn you.
