After the feast thrown for the win in Battle of Winterfell, Tyrion went to his chambers where he had just sat by the fireplace with a cup of wine when the door creaked and in stepped no one other than Sansa Stark herself.
"My Lady, what are-"
But Tyrion didn't get the sentence out and he almost dropped his wine glass when Sansa suddenly dropped her nightgown on the floor and stood in front of him in full nakedness and declared "I am ready now"
"Ready…for…what?" Tyrion asked, almost choking on his wine. '
Sansa couldn't help but smile, "I am ready to make love to you".
Tyrion just looked at her, incredulous for a minute and then stood up, picked up her night gown and handed it to her, "Sansa, please put it back on and sit by the fireplace with me".
Sansa did as bid.
When she was fully seated, it was Tyrion who started the conversation, "Sansa, what sprung this on?"
"Ok, I'll explain myself and you are probably gonna think that I'm insane, but I don't care."
Tyrion just nodded and Sansa continued.
"OK, remember on our wedding night you said you wouldn't share my bed unless I wanted you to. Now I know that a lot has happened since that day but I couldn't care less. I regret all of it. I regret leaving with Littlefinger, I definitely regret marrying again but I don't regret our marriage. Iwas stupid to leave you, I know that now."
"So, you want to sleep with me now, because…?"
"Because I like you a lot, I trust you, you are the only Lannister that has ever shown kindness toward me and maybe I'm not in love with you right now but I believe that given time it's gonna happen for us".
"And what about everything you said in the crypt about Daenerys being an obstacle for us?"
"After that I was so scared, I thought I was gonna die and you were there and I realized that it doesn't matter. I want to be with you no matter what and I don't expect anything from you concerning the Dragon Queen".
After that Tyrion had nothing else to say, so he stood up and closed the distance between them and went in to kiss her to which she didn't object.
"Then there's really nothing else to say" he smiled, being happier than ever and they walked to the bed.
