[...thinky quiet for a second, you could have put that more clearly, bro] That...sounds like a real mess. I don't envy your friend, I have to say.

Advice, though... well, I'd say she's probably got the right idea, to be honest, if she can keep that up. Messing with your timestream is one of the big Don'ts of time travel, if I picked anything up from that year. The Doctor can tell which events are fixed and which can be changed, but us normal folk can't. Pulling the wrong string on the timestream could unravel the whole thing.
