Okay, so I combined two prompts. The weekly prompt of "First Meeting" and Rage's guest prompt "Not for all the cheese in Ferelden." And yes, I took a few liberties, but it seemed to work in my head. 
It was at the first of one of their few visits at the Pearl that Alistair and Marlana had the “wonderful” opportunity to meet one of Zev’s great friends: Isabela. He’d sworn up and down that they’d like the female ship’s captain. Very bold and daring, had traveled to all ports of Thedas, the tales she could tell and even better, she was a skilled duelist who was known to teach her tricks to those piqued her interest. At Lana’s dubious expression, the assassin grinned, “Yes, yes, I know that the Pearl is a ****house, but you said the good Sergeant Kylon was looking to have you oust some annoying mercenaries, no?”
Lana looked over at Alistair who shrugged, “Can’t hurt I supposed, but this is someone that Zev calls a friend…”
She smiled faintly, “Are you implying something? Since he calls both of us friend.”
“Wellll, you are kind of troublesome…” He grinned and ducked her mock slap.
“If I’m trouble, what are you?”
“In up to my neck and rapidly sinking. And not regretting a moment.”
Lana’s eyes narrowed as he grinned at her, daring her to say something. Instead she laughed ruefully, “All right, Ser Sinking, let’s go see who in the rest of the troublemakers wants to go on our little expedition there.”
It wasn’t terribly surprising that the rest wanted to go, though she didn’t really want to know why Wynne, Morrigan and Sten wanted to go to the ****house, and didn’t dare ask. The really disturbing part was that Shale expressed curiosity about seeing a “den of iniquity”. She very firmly decided she didn’t want to know where the golem had picked up that phrase, especially the way Shale grinned as she said it.
Sangra, the “proprietress” of the Pearl, was quite pleased to see Marlana when the Warden told her that she was there to deal with the troublesome mercs that didn’t seem to want to leave. When Sangra got a good look at those accompanying Lana, she seemed momentarily at a loss of words, particularly with the Qunari and golem. Fortunately, it was easy enough to send the ruffians packing with a little gentle persuasion on Marlana’s part, especially with Alistair looming over her shoulder.
Pleased that there wasn’t any violence to disturb the guests and the workers, Sangra gave them a healthy discount on their drinks for their visit. As they sat chatting idly, and Lana was most definitely not going to ask where Morrigan and Sten had disappeared to, that Zev brought over the captain to their table. A tall, voluptuous woman with bronzed skin, dark golden hair and hazel eyes dressed in tightly laced, white leathers that left nothing to the imagination, Isabela was most definitely trouble. And not what Alistair would consider the good kind like he did with Lana.
Sapphire eyes regarded the woman somewhat warily, but their owner gave a polite smile and genially invited the duelist to join them. Isabela proved to have a deep throaty purr of a voice as she explained how she knew Zevran. She regarded the slight woman thoughtfully, and the dual blades at Lana’s back even more so, “Zev tells me that you might make a good student, Marlana.”
Lana nodded cautiously, “He said there might be a few things that I might find interesting.”
The smile she got in return was disturbing. “Indeed, but I would need to test you first. And there is the matter of payment of course.”
“What manner of test and payment?”
“Oh, it can be the same activity. See if you can beat me in a game of cards, or…” She trailed off musingly.
Lana became even more wary, “Or what?”
Isabela’s smile turned lascivious as she eyed Marlana up and down in a way that made some of Zevran’s previous looks seem positively tame. Lana could feel herself turning red, she’d never had anyone make her feel that dirty, and from the corner of her eye she could see Alistair flushing in embarrassment. But she could also see the way he clenched his jaw, he was…jealous?
The duelist laughed, “Oh my dear girl, have you never had anyone admire you before? Particularly that handsome lad that doesn’t leave your side?”
Refusing to look at anyone as she tried, and horribly failed, at controlling her blushes, Lana mutely shook her head.
“In that case my dear, I can teach you so much more than just the use of your blades. And no need to be jealous, Alistair. You’d be more than welcome to join in.”
Both of them turned even brighter, if that was possible, and Isabela laughed merrily, “Oh Zevran, you find the best surprises. Such a pair of lovely, young virgins.” Clearly amused at their expense she asked, “What will it be, sweet Marlana?”
Faintly, “Thank you, captain, but I think I’ll pass. If you’ll excuse me, I’m going out for air.”
As Lana walked off without looking like she was running, she didn’t hear what Isabela asked Alistair, but she did hear his response very clearly as he scrambled to join her, “No. Absolutely not. Not even for all of the cheese in Ferelden.”
