i like to think about dennis and robby being together so long that they start to pick up mannerisms from one another. dennis starts to rub at the back of his neck when he's nervous and cross his arms when he's listening to someone speak. robby starts to scrunch his nose when he's disgusted and tilt his head when he's confused by something.
i especially like to think about dennis picking up a little yiddish from robby. the first time "oy gevalt" comes out of his mouth, it feels so natural that he doesn't even think about it, but trinity gives him a knowing look. the first time dennis unthinkingly describes something as "farkakte," dana rolls her eyes and makes a comment about physically separating him from robby. when dennis mutters something about princess being a "yenta," it feeds the rumor mill for days.
for robby, it's the greatest thing in the world. nobody he's ever dated has really stuck around to pick up any of his yiddish phrases, and hearing them from dennis reminds him so terribly of home, of childhood, of dinners with his bubbe and zayde. every time dennis tells trinity to stop kvetching, or tells a med student to do something with chutzpah, or complains about schlepping somewhere, robby wants to wrap him up in his arms and never let him go.
