@Zercer Its just that, its one of those ideas that it sounds great on paper (for a given value of great), but if you take a step back and think for a moment, its actually a horribly monstrous disaster. Not because of the idea itself, but because of the sheer amount of work for an idea that would be essentially pointless.
If its about having family for Steele, there's the Rival, Shade and Astra.
If its about exploring the interactions and relationships, there's the Rival, Shade and Astra.
If its about banging the family, there's the Rival, Shade and Astra.
This isn't meant to be a disparaging reply, quite the opposite. You have an idea, develop it, work on it. But at the same time, perhaps realise its not the best idea for TiTS.
