Thank you. I'm not (as you may have guessed!) much of one for maudlin sentimentality myself, and it's not something that I really see fitting Jack, either. He's got so much past behind him that he has to keep looking forward, otherwise he risks just getting lost in wallowing. But there's no harm in occasional moments of reflection, so long as it doesn't descend into moping.

(or, 'why you will never see me have Jack hopelessly pining after his time on the TARDIS' ;))
