The Master was staring at the extra TARDIS inside the Doctor's TARDIS.

"You actually grew yourself another TARDIS?" The Master asked jealously.

"I'm sorry, but I'm keeping that, but I will help you grow your own TARDIS later if you want." The Tenth Doctor says carefully.

"I would like that." The Master stated thoughtfully.

"Remember that you promised to avoid killing Humans inside my TARDIS and I mean both of them!" The Tenth Doctor Proclaimed watching the Master's reaction.

"I will behave myself, don't worry so much about that, but we need to plan our escape now!" The Master responds.

"I'm taking us into outer space, check the TARDIS Internal Sensors for Borg Drones." The Tenth Doctor orders.
