"Oh, excellent." Not quite Mr. Burns, but you can bet that on the other end of the line, Gawain is rubbing his hands together. "Because we were thinking, that is, Gareth and I--"
"What's this 'Gareth and I' business?" the man in question can be heard to say. "I'll have you know, Mordred, that it was his idea." "I don't see you stopping me." "That's because it would be easier to smash Mount Everest into little tiny pieces."
"Anyway," Gawain continues on, "what I was going to say before I was so rudely interrupted by a certain someone was...Would you fancy coming over to our place for a bit?" A pause. "Not to stay, or anything, if you don't feel like it. Though we've got room if you need it. Just to have a bite to eat. And talk." He sighed. "I think we need to do that."
A person who knew him well might suspect that Gawain was nervous, from the way he was starting to ramble.
