It's probably a good thing Seth doesn't easily blurt out the first thing that comes to mind, because if he did then his response to Gabe hoping to see the 'hunky archaeologist' for breakfast would be 'I wish'. As it is he just lets out a small snort.

"Yeah?" he answers, twisting his head a little to look at Gabe with a small smile. "That's good. Communication, and all that." Not that Seth is in a great place to give advice on that. He's not particularly good at it himself. But supposedly honesty is an important ingredient to a healthy relationship. And he'd like Gabe and Johnny to be happy and healthy.
