"Listen, your way makes no sense. I do not take kindly to your insult to my vhal and in other times might have asked you to dance, but let's think about this again, calmly."
"There are two possibilities. Possibility 1--this is an innocent keep with no enemies about. In this case, it is perfectly fine to send in Dagobert with just a few people, but nothing is lost by sending all of us, including you Rowan, since there is no issue of the enemy recognising you. So both are equal in this case. Are you with me so far?"
*Lasair pauses for consent.*
"Okay, good. The other possibility is that the enemy is indeed there. If this is true, Dagobert's recklessness ruined any possibility of subterfuge, since he announced to them that we came here chasing a villain. Thus, if we send a few people alone, we have divided ourselves and the enemy can eliminate one group first and then the next. If we send in everyone, they must fight us all at once, and we are stronger. Thus, sending everyone is better in this case."
"Since sending a small group is equal in one case and worse in the other, and sending everyone is equal in one case and better in the other, there can be no possible reason not to send everyone, yes?"
(OOC: Yes, this had a bunch of talking, but Lasair will not accept another incident where Dagobert wanders off in the middle before the discussion is over and the party reaches a consensus--if he starts doing that, she'll retrieve her pen and paper and Suggestion him to write an essay about the ill effects of recklessness until she tells him to stop (which will keep him busy for up to 5 hours) )
