10th brick? Brendan asked Brain to watch Tug's house to see if Laura left it while he was at The Pin's trying to avoid a war. When they went to get the 10th brick so that Brendan could test it, it was gone and it was revealed at the end that Laura stole it to ultimately cause the slaughter.... But if she never left Tug's house during that time, how did she steal it? 10 Points for the best explanaton. Thanks!

If she did manage to slip out of Tug's and into The Pin's, how did she get in and out unnoticed.... Or, is this maybe a plot hole?
