The only way if he was going after the espadas was he needed somebody to help him if he was to kill them all arrancars, hollows and the espadas. Darque needed someone dedicated to fighting someone like a hero but he didn't know anybody of that nature but hearing these stories about an white armor guy. Maybe that was the guy he needed to fend off against his enemies yet revenge against his kind but he would have to protect his friends or whatever. If they were to die then it would be all over and yet he would hae to fight whatever large number of espadas there were also this woman who wanted to avenge Aizen. Darque would have to deal with that problem too he was strong enough to deal with anybody and his zanpakuto powers would handle any big threat against him. The only thing he could do now was to find this white armor guy and convince him to hep destroy all arrancars or espadas. Darque then thought what if he were to destroy them all what then what about himself maybe when the time was right all the threats these hollows, arrancars and the espadas were all dead and gone. Perhaps when the time comes he'd allow a shinigami to take him down so maybe he could atone for sins of all those humans he had devoured all those years ago.
He could let that get him down, Darque will deal with that when the time comes right now it was onto business. Darque needed to find white armor guy "Alright, Espada man......SHOW YOURSELF"
