I'd wager that Eric knows more about her than pretty much all the other men she's dated on this show. They all seem to miss or underestimate some kind of basic thing about Calleigh that spells the demise of the relationship. Not that I think she's necessarily an easy person to date -- she's somewhat complex. lol And she needs her space, and her freedom, but still I'm sure wants to be taken care of and treated from time to time. So I'd wager she's probably kind of a tough balancing act if you don't know her really well. Which, thankfully, Eric does.
