"Can I come?" Mickey asks gingerly, not wanting to be left behind again. The Doctor just asked Sarah Jane, so he must be willing to take on other passengers.
"Not with you" He indicates Sarah Jane, he looks at the Doctor "With you. Cause I'm not the tin dog and I wanna see what's out there".
The Doctor looks at Rose. She mouths 'no' at him.
"Oh go on Doctor. Sarah Jane Smith, a Mickey Smith. You need a Smith on board." Sarah Jane encourages.
'Okay then, I could do with a laugh."
Rose looks away disgruntled. She had been okay with Sarah Jane tagging along. She liked her and she couldn't imagine Sarah Jane would stay on board for very long. She must have a live out there.
Mickey looks pleased, very pleased.
"Rose is that okay?"
"No, great. Why not?"
Her back is still turned towards him and she will be damned is she lets him see her face. She likes Mickey, she does, but it feels like he will interrupt what she and the Doctor have together. More than Sarah Jane could, even though she actually had a history with the Doctor. For some reason she prefers having his 'ex' around to her own ex complicating matters in the blue box..
The Doctor and Sarah observe the both of them and feel the tension.
"Well I'd better go." Sarah Jane breaks the silence. Grabbing Rose by the arm and turning away from the men. This brings up the other issue Rose was struggling with.
"What do I do?" Rose questions. "Do I stay with him?"
"Yes." The older woman answers resolutely. "Some things are worth getting your heart broken for." And she hugs Rose.
"Find me, if you need to, one day. Find me."
