Once Edwin and Charles figure their relationship out, normalise Charles being super silly ™ in dates with Edwin.
This, by now, is their 2nd or 3rd official date and they are returning to their flat. Hand in hand they walk down the lamp lit London road leading to the office flat. Edwin is reveling in the slight warmth of Charles' hand in his, and atmosphere of the night. But suddenly, Charles takes off on a sprint, Edwin fumbles, calling for him and then begins to run after him. But the head start that Charles had means that he is already at the flat whilst Edwin is climbing the last flight of stairs. To his shock, the door is thrown open and Charles is kneeling on one knee, with one hand outstretched for Edwin and the other holding the door. His head is almost brushing the floor, but without looking up he says between ragged breaths:
"Come through, your honour. "
Edwin gently lifts his hand to his mouth in a shocked movement, but places his hand in Charles'.
"Thank you Charles, really I've never had someone do this for m-"
Edwin can't say anymore because in a single, swift movement, Charles sweeps around the stand behind Edwin, leaving his hand gently hovering for Charles' used to be.
"Anything for my best mate. " Charles breathes into Edwin's neck, winking. Suddenly Charles hands are sliding Edwin's overcoat off and hanging them on the nearby coat hanger.
Edwin has stopped working and has disintegrated into a furiously blushing puddle on the floor.
