spotted minor flaw in one of the bests if not the best episode

In the episode where they show the escape from the beginning through to the very end where they just walk into switzerland there was a problem. not that it's important really since this was a fantastic episode. when they are crawling through the sewer/tunnel in the castle, they come to an opening with bars, they manage to get some of the bars off, but it's very, very tight. only one skinny guy can barely get through since they only got like one of the bars off. I'm thinking ok fine but they are all carrying huge big luggage bags of stuff they absolutely had to have if they were to make it all the way.how in the hell can they get the bags through? no way, but then they show them suddenly appear outside WITH the bags. they could not have gotten those bags through that narrow space and thus would have been screwed right then and there. But what a great episode as it was nice to see them trying to survive outside the castle. very realistic and well done. imagine the terror of being so close and worrying about being caught at the last second a few feet from the border.
