[Espy]

An assassin/spy working undercover in a club, who keeps a close eye out on the protagonist on orders from the leader of their organization, and eventually follows him out one night to warn him of an impending ambush. They join the team after the protag makes an unpredicted turn and walks right into the trap, and the assassin throws any and all disguise protocols out the window to to take out the attackers almost before the protag notices they're there.

...I almost want to draw this thing out now.
