Marcia - formerly Mark - just let herself be carried on the ride just as to her own fantasies. Due to her trauma, she did not even care about her new feminine desires bubbling inside of her. Patrick. Oh, Patrick! He was a knight, he'd saved her, he was handsome, brave, dashing.... A true knight, no doubt! And he'd call her beautiful, and had promised to marry her! How gallant was that?!!? Adding to his valiant nature, which did not spoil anything, of course! And he'd been so, so gentle!
All to her reverie, Marcia could not know that in spite of her undeniable beauty, Patrick had no real intention of marrying her. Sure, he had to maintain a certain set of standards and he DID find this maiden beautiful, very much so, yet he knew too that he could not seriously consider a wedding. She was expecting six babies, for crying out loud! If not more!... How was he to deal with that? It was just too much for him, so he sincerely hoped that he'd find a mate for this poor woman as soon as possible. Getting stuck with this woman and her future brood of children was not his notion of a good future. As such, Sir Patrick prayed to all the gods that there would be a man ready to take in Marcia, and fast. And if no one was volunteering - which would not surprise him - he would find one further away and incite a prospective husband with money.
Indeed, Sir Patrick took Marcia straight to his castle, ordered for her to be washed and thoroughly cleaned while he investigated around the busy town. And he came back happy because he found a husband for Marcia, thereby making him not responsible for wedding a woman with trouble brewing in her belly.
