Petting the console of the TARDIS one more time, trying to reassure their baby that everything will be okay, she heads away walking towards the ramp. Hearing the commotion outside she pauses before going out peeking out the crack in the door watching in amusement at the questioning the Doctor is getting.
With Jack's gun back in his holster, she decides its a good time to come out. She pulls back on the door and rushes outside.
Passing the Doctor she runs towards her World War II dancing partner, "JAACCKK-It's me Rose!"
