Your marriage was a sham.

Carefully fabricated by you to maintain appearances, to continue your assassin work without arousing suspicion.

Colin had his own reasons for being married to you.

They didn't need to know anything about each other, no questions, no emotions involved.

Just business.

"What are your favorite flowers?" Colin suddenly asks, while glancing at his phone. "You know, in case someone asks," he adds, trying to appear indifferent.
