Hissra's proposition sounds like our ideal plan, but I am afraid that I cannot participate in it. My posing as an elven slave would easily attract unwanted attention and probably rise suspicion from the slavers. Although I am unfamiliar with the grounds here at Denerim or the alienage, the tattoos on my face and the attire I am wearing signify my Dalish origin and I am fairly certain that no Dalish would be captured as slaves.
However, I do believe that Hissra makes a valid point in being able to come up with a plan that will ensure our safety, including a back up plan in case if something goes wrong. Conlan as a seller with Hissra and Karashok as his bodyguards would be our Plan A, Lalin posing as a slaver -- when she actually is not -- is our Plan B. This also lets us throw in more than two people in the trap, if that's what it is.
If Lalin is alright with this scenario and there are not any better ideas, then I believe this plan is the most liable for our safety. I must make an assurance, however. While I am aware that violence may occur during this meeting, we are here specifically to extract information on the whereabouts of the slave captives, I ask that you do not draw your weapon unless it is absolutely necessary.
There is one thing that must be straightened out before we carry out this plan. Lalin posing as an slave will ensure us access to the slaver captives, if her trade happens at our meeting place instead of where the slaves are held, then I suggest we find a way so that she can somehow communicate with us on the outside so that we know where she is at. I...do not want to put her in any danger unless there is a precaution.
