To be fair actually describing the barrier was probably a good idea, if only because certain individuals now trapped in said barrier probably would have tried to go over it or something with their 'manipulate air' tome.

As far as things go now, all the previous discussions we had had about the heist mission was with regards to using it as a mechanism to both influence the plot, and to use it to allow Alex to meet the group while re-establishing his credentials as a thief who does thief stuff (Since the last time he did that was at the beginning of the RP and he got caught). Given that I know from previous statements made that you guys want to move on to the climax of the RP and the ending, this relatively sudden move to link up Alex and Meihou with everyone else without warning seemed to contradict that and make it look like you guys just wanted to have them get together so you could go straight into the ending/final confrontation of the RP, where Alex's main value to the group would be 'has a Relic' as opposed to anything specific about his character. 

I mean, I am curious to know how getting arrested would have let him link up with the group, but fortunately we have a relic so that isn't a problem.
