Female!Ten, Morgyn
She didn't crack a smile as she threw the levers, pressing buttons, and all but glared at the jury-rigged console as she sent the TARDIS dematerializing, despite the Doctor's frantic attempts to stop her, and get the doors back open for her companions. The Master didn't want them in here, didn't want them to interfere with her plans.
Besides, that would give the Doctor allies against her, and it was bad enough that this was the Doctor's TARDIS in the first place. Though she was responding well to the Master's input.
Well, so the Master thought, until the jolt of landing told her something was wrong. She glanced at the screens, frowning slightly in puzzlement. She'd intended to take them into the Vortex, then find a place she could deposit the Doctor that was out of the way in time and space while she worked on returning to the power she deserved. This... wasn't the Vortex, and it wasn't someplace she recognized as safely out of the way, either.
