He owes her a ring, and... His bride to be makes him consider giving up drinking!

Ysolda explained how Viktor had apparently told her about the love of his life, who he knew nothing about, even giving him a story he couldn't have come up with even sober, again, making him question what in Oblivion was in that damn drink. Upon Viktor explaining what little he knew of last night, Ysolda sighed, and said, "Well, I gave you a ring you promised to pay me back for later for your love. I suppose you'll have to go get it back. And since I know you're good for it, I'll also tell you where the wedding was supposed to be."

"That... Would help, yes," Viktor nodded.

"You said you met her at Witchmist Grove, and the wedding would happen at Morvunskar," Ysolda explained. Viktor quickly looked at his map to find both locations were East of Whiterun. "Shame. I was looking forward to the wedding."

"My Thane!" a rather haggard looking Lydia shouted, pushing through the crowd at the market as she spotted Viktor. "What happened? I've been searching everywhere I could think of for you!"

"... it's a long story that I'm still putting together the details of," Viktor sighed. "I'll tell you what I gathered on the way to our next destination."

...

They rode to Witchmist Grove, Lydia behind Viktor, who was slightly lamenting the hard armor they both wore keeping him from enjoying the feel of a lovely woman's assets in his back. "...sounds like quite the night," Lydia summed up after Viktor finished explaining what he had put together.

"No kidding," Viktor agreed. After several hours passed, they arrived to a hut... And a hagraven exited it, and grinned at Viktor as he and Lydia got off the horse.

"Darling. I have been waiting for you to return to consummate our union," the hagraven said as Viktor went green in sheer horror.

Lydia stared in surprise as she saw Viktor's "lover," before she started laughing herself sick. "Oh by Akatosh, that's absolutely hysterical!" she laughed.

"...I'm seriously considering giving up drinking now," Viktor groaned.
