Actually, now you mention it, your use of 'silly buggers' isn't quite right. Usually someone will say, "Stop playing silly buggers' to someone who is clowning around, whereas in the context, it seems more like Spike is saying, "Let's call it quits'. You could change it to that, or have him tell Ethan to 'stop playing silly buggers' and let him go.

And I don't mind you asking me about Brit stuff, as long as I can ask you about American stuff.

And no, I don't think I saw your Spru fic. Can't think how I missed it. Will go back and read asap.
