It's more based on the psychology of Catherine rather than putting them in the personality roles of the characters.

Remember, the nightmares are given to unfaithful men to punish them/test them for their misdeeds. Twilight is the woman who loves him.

Catherine is a succubus, she matches the ideals of whatever man is her target. Dissy isn't exactly attracted to bubbly, bouncy seductive blondes.

He's attracted to Tavy because she compliments him. She's the same colors as him, wears a bowtie, and her mystery and cold nature is quite attractive to him. He sees her as a challenge he wants to take, and thats why he's got such a weird crush on her.



Basically, Twilight is that home life. She has a child, wants a romance.

Wheras Tavy isn't that type, she's one who wouldn't be too emotionally attached to things, and doesn't seem the type who would be overly clingy to him or his adventures.
