that works super well for me, yeah. it's around that time that he fucked up royally on one of the missions he was handling, to the point where an aegis agent and a close mentee was killed (i think i'll keep this agent as an npc for now). maybe tatiana was working on behalf of her program as a liaison of sorts and witnessed all the shit that went down? so he'd want to help her any way he could, almost as a way to assuage his guilt of mishandling the now-gone agent's safety.
