Ves could not make an immediate decision on Gloriana's proposal. A radical shift in strategy had enormous implications for his life and the lives of his clansmen.
Instead of making an ill-informed decision, he decided to sit on it and let the situation develop a bit more. He still needed to handle a few affairs such as meeting with the MTA, completing the Ghost Project and preparing for his departure from Davute.
"Just because I'm impulsive doesn't mean I always live my life this way!"
His wife might have tried to use this hasty maneuver to present the illusion that Ves needed to drink the poisoned chalice right away, but he chose to set it aside for later.
There was no obvious reason why he should rush and issue his verdict right away. So what if the Vrakens sent their precious ace pilot to his location on a superdrive carrier?
That ace pilot could sit right outside and wait until Ves was ready to handle her case!
