It wasn't until they were halfway through transferring Flossie Wright that they reacted with hindsight. A chord, seemingly severed by severe shock, seemed to suddenly reconnect, prompting new considerations about Flossie's intentions.
Even a fool might take the chance to escape given the circumstances. Having defeated all of them, escaping would have been a simple matter for Flossie. However, she had taken them by surprise, climbing directly into their car. This was not the behavior of a fool, was it?

Just thinking about it was enough to break them out in a cold sweat.
