Time Love and Tardis

While the Doctor is talking with a Time Lord, his TARDIS and a replacement TARDIS have a telepathic conversation about whether Time Lords love their TARDISes. The Doctor's TARDIS believes her master loves her, but the replacement TARDIS isn't so sure and tells her that TARDISes are meant to be used and then replaced with a newer model. However, although the Doctor is offered the replacement TARDIS, he decides to keep his own TARDIS.
