You know there is this big plot hole in the present situation since the gold is within that chaperon's pocket so even if Lawrence doublecrossed them at the gate it does not help Lawrence out of his financial problems therefore it is meaningless for Lemerio to think and/or consider Lawrence would doublecross them before entering the gate. There is also the problem that since Nora is the key in smuggling in the gold through the gates without a hitch, it would be not in their best interest for them to roughen up the relationship with Lawrence since Nora was introduced through Lawrence for this plan.
I wonder what the three from Lemerio was planning to do when all of them came out of the woods together?
