"More the TARDIS than my own ability," AL admits. "I can't time travel with passengers. It's the teleporting where I can bring one other person along. And I wouldn't trust my powers to get me here on time, either. It's very unreliable." She shrugs.

"The TARDIS isn't all that reliable either, lassie," says Jamie, earning himself some dirty looks from the Doctors.

"That's true," AL agrees, and the dirty looks shift over. "What? You yourself admitted it once." That statement was directed at the Fifth Doctor.

"Well, yes," he allowed, "but..."

"But the TARDIS herself told us that she always took us where we needed to go," adds Eleven.

"That is also true," says AL. "Hm...I guess the De's the only reliable time machine out there." She grins and ruffles Dee's hair.
