Re: confusion in relationships.
In our case it can be confusing for him, but he has yet to officially meet any of us but Earth Listener sense they are the ones dating not anyone else. The rest of us have no real feelings for him. Because he wants to spend his time with Earth Listener and we (usually) have control over our who his fronting and when he doesn't have to deal with random switching.
So far at least with Lunatani, Kardegray, and Zeoriel he can seems to be fairly keen on noticing our differences in behavior, voice tone, and such. However hat is only four out of nine.
