I didn't get a prompt for this but it's just thought of the idea based on the scene in S1E01 when he goes to say goodnight to her and they share cute looks. I'm so excited to see their evenings together in Series 6 now they're engaged.

Their night-time routine of twenty years was not to be altered no matter the goings on of the house, therefore despite a long evening dinner, Mr Carson would still make sure he bid his fiancée goodnight before heading up. His protest against her staying up so late fell on deaf ears as she insisted she always had books to go over. They both knew however she stayed up to make sure she was the last person he saw every evening, and the first in the morning.

All too often nowadays he would stand in her doorway simply watching her, the reality of their situation still unbelievable to him, until she turned around that is, then her smile reminded him it wasn't a dream – she really was his love. His betrothed.

After slowly approaching her, he faintly cupped her cheek and tilted her head upwards.

"Goodnight my love." He pressed a soft kiss on her forehead.

Her eyed fluttered shut and she savoured the tender moment he had saved until they retired for the evening. Before he could make it out of the door she stood and called him to a halt.

"Charles? I was wondering if…what is it?" She'd started but his intense stare when he turned around caused her to falter.

"You've…never called me that. In the twenty years we've been acquainted, I've never heard you say it."

"Oh. I suppose I've not."

"Say it again."

"Charles."

He closed his eyes and sighed as her brogue rolled over the r's and extended the s.

"I had wondered if tonight perhaps, you'd kiss me goodnight, properly."

Since he proposed on Christmas Eve she hadn't seen, he'd barely been able to conceal his warm gaze towards her each time he saw her, the look implied his very heart would explode with love.

"Of course my lady." She'd thought with his voice, whispering would be impossible but she found he could lower his voice considerable and achieve a gentle rumble along with it.
This would be their first kiss and her heart beat wildly in anticipation as he approached her. Too slowly for her liking so she raised herself onto her tiptoes and pressed her lips to his, steadying herself by holding onto his arms. His slid around her back.

Their kiss ended quickly as their breath waned, thus they were forced to pull back and lay their foreheads together, now reluctant to leave each other for the evening.
Elsie could feel him smile before he pressed the daintiest of kisses over her lips again, she couldn't help but laugh, overjoyed at the feelings he caused. Her laughter was infectious and soon the elated sound rang out from them both and they embraced tightly. It was some ten minutes before they released each other and Charles departed with a final delicate kiss to her forehead.

"Goodnight, Elsie."
