If that Wikipedia article is correct, which of course they sometimes aren't, Heather doesn't have to register anything: she is considered a citizen by Britain, unless she's specifically written to the British Home Secretary asking not to be.
Congratulations, Heather, you're a Brit. Have a cup of tea!

Like the rest of North America, it's hard to find anyone who can make a cup of tea worth a shit in New York, and I'm too lazy to do it myself. I'll pass.
As far as I can tell, Heather is still able to register for British citizenship.
At one point, I did have both passports. At the moment, they're both expired. I wonder how much of a PITA renewing the UK one will be.
I don't know that it would really make a difference but it could complicate getting a security clearance.
Oh, they'd hit the arrest record before they even got there. The type of people I imagine I'd come across dealing with things needing a security clearance won't find those stories nearly as funny as I do.
