"A favor?" Irina repeated, Ethan could already imagine the grin on her face as she spoke, "according to our agreement, a favor will cost you Ethan."
"I'll offer a year's use of a custom version of Sentinel for free," Ethan offered, "with its attack use, not just for defense."
There was silence on the other end for a while and Ethan heard her let out chyort, which meant damn it.
Or devil, which suit Ethan pretty well in Irina's current mind. He knew that she'd use that 'favor' as a way to get closer to him so he offered a deal hard to overlook.
Of course she knew Sentinel's capabilities, especially since it had easily defended against one of the best hacking groups known in the Underworld....
The Vigilants.
She also knew the capabilities of its attack mode since that was the reason they were in this contract in the first place.
So a custom one would definitely be a lot better than the one they currently had.
