Oh, if Kings is a friend of Bill's then Fleur is even more excited. She'd have been a bit grumpy/bitchy there for the last few years while Bill was on potion though, because she wasn't. Leads to wonder if Kings knew she wasn't or she knew he wasn't. As she never really has been, because of the Veelaness.
I like that. Neville really needs more interaction/purpose. He's been off for awhile now and ever sense he's been working in the pub trying to help anyone who needs it. If he and Kings somehow managed to figure out they were on the same side, Neville would enjoy his companionship.
