there’s a note in his voice — something acidic and out of tune , something she recognizes far too well . the sound of bitterness , looming heavily inside a heart , so thick and overwhelming it could crush one’s lungs . yet it’s frightening , too : she knows its hunger and its anger as well , so she keeps her distance , standing a few safe feet away from his turned back , unsure — yet feeling every vibration of sorrow in his words .“ i’ll go ” , she concedes at last , hands buried in the pocket of her jeans , head hanging low , like a child , like she’s lost all her confidence . “ but you — you got my number if you need , you know , anything ” . turning to the door , robin sighs and lingers for a second . “ i’m sorry , doc ” .
