The actress who plays Rose is transgender and, based on a line from Donna in The Giggle, so is Rose. That suggests that Donna didn’t name her Rose, she chose it for herself.
So is it a coincidence? Is there some significance?
It would be interesting if they revisited it.
Presumably similar to how the plushies she made were based on Donna’s time with the doctor, the name Rose probably comes from that too
I forgot about that. That would add to the mystery. I really like Rose, so I hope she comes back anyway. She was definitely underused.
