If this doesn't take a terrifying turn for Aki then i'm guessing that this is where Zinovy is disabused of the notion that she's just being Tsundere. Or maybe not; as much as Aki is the least imaginative teenager ever when it comes to communicating with her keeper, Zinovy's density is on the romcom protagonist level. His mom was able to figure out in a couple days that, "Wow, this human is eerily smart," but Zinovy is with her every day and he never questions how easy she is to take care of when someone isn't kidnapping her.
