It's a relief that the other doesn't take too long to come to a decision, her eyes scanning, mind running rampant in the seconds between her protests and her choice. See the field, Doctor, notice the details, come up with the plan. It is what you did best.
"I believe jury's still out on that one!" Survival instinct was always stronger than 'reason', so it is no surprise that the other runs into the box, promptly turning behind after her and starting to stride towards the TARDIS. "It's not just any old wooden police box--!"
Her hands place on either sides of the box just as she's about to take a step in, momentarily pausing to glance around. That blue coated fence-- Surely not.
One thing at a time, Doctor.
A breath, and she steps in, starting to run towards the console as the doors close behind her. "And I promise we'll get around to answers!" Now, she was in her element, flipping switches and pressing various buttons as she runs circles around the rotor, mouth running mile a minute as she, for all intents and purposes, exposits.
"Cybermen aren't meant to be in this time zone-- Not the Mondasian kind, anyway. Likely fell through some sort of time rift or a dimensional pocket or a long forgotten remnant of an old expedition. --I mean, look at them, they're busted.-- But! That gives us an opportunity. Their shields are faulty, which means they are susceptible to any sudden bursts of concentrated energy and/or radiowaves, and/or energy-as-radiowaves. The same kind of energy my TARDIS just happens to give out if I ask very nicely--"
Was the other one even listening? That was hardly the point. What was the point was the way she grabbed onto the lever, pulling it at the end of her sentence as if to underline it; the rotors whooshing once, twice, before coming to an abrupt stop, the console room shaking but for a moment.
"--A bunny hop. Not the most elegant trick, mind you, but it should be sufficient to shut them down." Then, a smile, somewhat relieved, somewhat crazed. "So-- About those questions?"
