('I cannot be the only one to survive this ambush,') He knew this.
Out of the sixteen Martial Squires that were ambushed out of the twenty-four, it would be far too suspicious if he, perceived to be the weakest Martial Squire as a grade-B Martial Squire, was the only survivor.
Such an outcome would be extremely hard to believe, and anyone who hears it will definitely find it very odd, even if they didn't suspect anything immediately. He was sure that Chairman Deacon would be very suspicious. He was also sure that Guildmaster Bradt would be quite suspicious too.
