Mary Ann was in her room, on the TARDIS, lying on her bed, when a knock sounded on her door. "Go away, Nyssa!" Mary Ann shouted.
"It's me," Gilligan said as he peeked into the room. "I was just checking up on you. Can I come in?"
"Sure, Gilligan, I'm not mad at you," Mary Ann said as she sat up on the bed. "I guess you heard all that happened."
"Yeah, I did," Gilligan said. "From the gist of it, it seems you can't change what's already happened."
"That's just it, Gilligan, it hasn't happened yet. My parents are still alive."
"Yes, but it's going to have happened," Gilligan said. "Am I making sense here?" His head was starting to spin at all this. Where is the Professor when we need him? Gilligan thought.
"Yes, Gilligan, you are," Mary Ann said. "Still, I have to try, Gilligan. Why else do you think we ended up in this time and place?"
"Gee, Mary Ann, I thought you were happy living on that farm with your aunt and uncle."
"Oh, Gilligan, don't get me wrong, I love Aunt Martha and Uncle George dearly," Mary Ann said. "Still, there are times that I've wondered what it would have been like had my parents had the chance to raise me. Would they have had any more children? So many questions."
"I understand, Mary Ann," Gilligan said. "In fact, I'd like to help you, if I can."
"Good," Mary Ann said and began to lay our her plan.
OOOOOOOO
In the console room, Nyssa and Tegan were having a discussion of their own. "We can't take off? Why?" Tegan asked.
"Some kind of localized distortion in the space/time continuum," Nyssa replied. Until it clears up, we're not going anywhere?"
"What's causing it?" Tegan asked.
"I have no idea."
