This was one of the first ideas that popped into my head when I started writing these one-shots x Please read and review :)
They don't fight often. They are too in-tune for that. When they do fight it is either playful bickering or cold silences. It's very rare for them to break out into an actual screaming match.
In this case it's somewhere between all three, switching between them at the speed of light.
The argument is about their wedding. It is not about flowers or dresses or cakes or colour schemes. That has been (mostly) left to Rose, or else Jackie would stuff them all into frills.
It is about names.
Rose says she wants to take the name that Chris uses in this world. Chris refuses, because that name isn't real. It's a fictional creation.
Tyler is real - and it's Rose. Why would he want her to change her name to be with him?
He'd fallen in love with Rose Tyler.
And, after all these years, names meant nothing to him. This would be the best name he'd had in a very long time - perhaps ever.
