I thought it was time Mickey got his voice heard after S2E6 - The Age of Steel. Don't own anything. Please review and make my day!
The departure of the tin dog
I had finally had enough of waiting for Rose, always listening out for the sounds of that blue box, so I decided to go with them. After that spaceship with those time windows to 18th century France, I realized what Rose meant – it really was like a constant adrenaline rush to travel with the Doctor.
When I got involved in the life of Ricky – my parallel life, I guess – I felt fort the first time since stepping onto the TARDIS that I had some sort of purpose. With Rose and the Doctor, I had mostly been the guy watching their backs. As I had discovered, I was the tin dog. And I was sick of it. So when Jake was about to head off into that zeppelin, I decided I'd had enough of being the tin dog. I was going to do something that mattered.
Rose did seem a little worried about me, and told me I'd better see her later. I was happy to know she still cared, although she only seemed to have eyes for the Doctor these days. But when I turned to have one last look at her before heading off, I saw that he got a slightly warmer goodbye than I had. Not surprising, really, since it just confirmed what I'd been thinking for a while already, but it still hurt.
How surprised weren't they when "Mickey the Idiot" was the one who saved the day! I definitely showed them that I was more than Rose's good-for-nothing boyfriend – although I guess I hadn't really been her boyfriend for a while now. And in the buzz I felt after my great success, I decided it was time Mickey Smith got his own adventure, his own story. So I stayed.
Rose asked me not to do it. When the Doctor told her they could never come back, she even told me she needed me. Anything to keep things as they were, with her two guys by her side. But I couldn't do it anymore. So I told her the truth – she didn't need me, it was just her and the Doctor now. I would head off with Jake and fight those robot guys. The tin dog fighting the tin men – that actually sounded pretty good to me.
