True Love
This is a duo that pops up quite a bit in the Bird People world. They have thus far only been seen with each other, though the man bears some resemblance to Nathaniel's drinking buddy. Neither of them have established names, and their exact relationship is ambiguous. As they're a man and a woman who spend a lot of time together, it is natural to assume they're dating, betrothed, etc., but they never display the sort of intimacy one might expect (though reservedness is not uncommon among bird people).
