love the "established hucklerobby but newcomers have no idea" trope
dana instructing new med students:
"if dr robby is not in the mood and you need to ask him smth that will make him even more snappy please do us all a favour and take dr whitaker with you to soften the blow"
• one day some student comes up to robby alone, stuttering "dr. whitaker said he's busy but he told me to tell you to listen to my report and not be mean because I made a mistake"
• sometimes dennis waves the student off "yeah you go, I'll stand here where he can see me, don't worry I'm watching"
so he's just giving robby the look across the hall and a nod of encouragement to the student
it all clicks for the newbies one day
dennis pops up in the hospital on his day off (because robby forgot his keys) and suddenly robby (whos been bitching the whole day) smilies brightlly, greeting him with a "hey baby" and a peck on his lips
dennis murmurs "hi, here's your keys and I need you to fix your attitude a little cz I've been getting complains"
robby snaps a look at trinity who just shrugs her shoulders like yeah I told on you, what you're gonna do about it
