In the time it took for the Scarlet Rose to pass through the territories of the Ordent Republic, Ves hadn't been spending his time in vain.
As someone who always indulged in paranoia, Ves never assumed the best case scenario happened all the time.
His temporary rational state did not diminish this aspect of his. Instead, he became just as paranoid as any casual probability analysis concluded that Ves would surely encounter a situation like this where the Scarlet Rose couldn't shake off her pursuers!
If not now, then later! Ves had to pass through too many star systems, giving his pursuers plenty of opportunities to prepare an ambush!
Aware that fleeing was not always a viable solution, Ves had to prepare another countermeasure!
If he was a qualified starship engineer with many different ship-related competences, then he would have decided to tinker with the Scarlet Rose.
