Rose leant against the doorframe, watching the Doctor as he fixed his hair into a less spiky style than usual, taking in what had started out as a tame (and rather attractive, if she may say so) stubble from his latest field trip and had surprisingly been allowed to grow into a proper, full beard. The red shirt he was wearing was different from his usual choice of colours, too, but for some reason still seemed oddly familiar.
“Not that I really mind, but is there any particular reason for the sudden change in styling…?”
The Doctor’s eyes met hers in the mirror, while his fingers continued expertly tousling strands of hair into a certain look.
“Well, Tony told his mates he’s going to introduce his cool sort-of-brother-in-law to class for a cool presentation, didn’t he?”
The blonde couldn’t help smiling at the obvious care he showed for her little brother, feeling warmed by how much making Tony happy seemed to mean to him.
“Aren’t you putting a little too much thought into that comment, Doctor? It’s just a school presentation… Besides, I should think having a proper, renowned scientist showing off a flashy experiment should be plenty cool, yeah?”
The part Time Lord shrugged a nonchalant shoulder in reply, but Rose could see the hint of a blush colouring the tips of his ears.
As she continued watching him fix his hair, taking a more appreciative look at his appearance (and the tight jeans he was wearing), she suddenly realised why the new look seemed familiar.
“Wait - have you been checking out the fashion section in Mum’s magazines?”
A beat of silence.
The high tone his voice had taken, paired with the sheepish look on his face (and the definitely pink-tipped ears now), were enough to spur her into a fit of giggles.
Once she’d calmed down enough, she soothed the Doctor’s flustered indignation at her reaction with a soft kiss, letting him know that she appreciated his caring.
Even if it was rather amusing.
Dedicated to @littlewhomouse (she’ll know why ;) ) and @tardisfangurl, whose initial suggestion of putting bearded!DT into a checked flannel shirt (which then turned into Hipster!Tentoo trying to be *cool*) sparked the random silliness x)
