With the plot about him revealed Alexander wasted no time formulating his own counter plan, one designed to turn the tables on the other side.
And the way he intended to do it was to take advantage of the attack to launch his own attack.
That was why he gave those kinds of orders to Remus and Hemicus.
And since the time on their hand was really short at best a few hours, the men wasted no time in trying to prepare themselves as best as they could.
Hemicus's job was relatively easy, he only had to find two unlucky servants and ask them to take over Alexander's shift from them.
And to this effect, he ordered them, "The lord has called us into his room tonight for some drinks. So you two are to stand guard instead of us."
