You know, I've been thinking about this more. I wonder if my interpretation of Laetitia in the XII is simply because fire and joy are rare in my life, so the negative attributes of Laetitia (such as being untethered, undirected, excessively visible, "high", etc.) are simply things that are balanced (or, perhaps, drowned) by my unusually watery nature.

That is to say, having any fire is rare, so having an excess of fire is nearly unheard of.
