Written for Challenge 230: Bauble / Babble / Bobble at dw100.
Summary: Donna is used to not understanding the Doctor.
Donna’s reasonably sure the Doctor knows what he’s talking about, he’s always pointing out how brilliant he is, but despite taking science at school, most of what her friend explains to her goes right over her head, just a meaningless babble of nonsense words. Time Lord science is a bit more advanced than anything taught in British secondary schools; if she could understand what he was on about she’d be a genius too, not just a temp.
Then things get a bit freaky and instead of plain old Donna Noble, she’s the Doctor Donna. Technobabble’s easy when you know how.
