Thanks, Louise, it does help.
I’ve noticed that there seems to be a lot of disagreement about the speech quotes (whether to use single or double) even among U.K. writers on absolute write. Must depend where you’re from, but I think what PLS was talking about here, and what I noticed looked wonky, was this: ‘Your sister sure got a lot of stuff‘, said Roddy. The comma should go inside the quote.
ETA: I don’t know what to think after looking this up. The Oxford Guide to Style says this, which seems to back up Ricky’s style:
Quotation marks, also called ‘inverted commas’, are of two types: single and double. British practice is normally to enclose quoted matter between single quotation marks, and to use double quotation marks for a quotation within a quotation:
‘Have you any idea’, he said, ‘what “dillygrout” is?’
This is the preferred OUP practice for academic books. The order is often reversed in newspapers, and uniformly in US practice:
“Have you any idea,” he said, “what ‘dillygrout’ is?”
