"Welllll, clone isn't exactly the right word." In fact, he hates that word, when used for the TARDIS or himself. "It's more like...twins? Mother and daughter? Two parts of one whole? It's all rather complicated. Since the coral that grew this TARDIS came from the TARDIS I was already bonded and linked with, it's got almost the exact same personality. Though maybe she acts a bit younger, since, well, she is! It's really almost exactly like me! Well, minus the human metacrisis part..." He beams, as he always does when he gets talking about the TARDIS, "I fixed the chameleon circuit! Well, no, built a whole new one. So it works, it can blend. But this look...it's familiar. Comfortable. It's...home. We weren't in a hurry to abandon the look."
