Really? Cuz to me it seemed as though he were sincere in his offer to the f!mage in origins in case she really needed someone to talk to. Even if it were to be in the case of him wanting to spend time with her, I'm more than positive he would be more than willing to hear her out if she had any issues.
It was kind of like this:
f!Mage: I shouldn't waste your time anymore.
Cullen: OH NO DON'T WORRY you can always talk to me, it's ok!
He said that in response to her suggestion that she was distracting him
I don't think their relationship, if you can call it that, was at the stage where it would be ok to offer a shoulder for crying on it. Such things require a deep emotional connection, imho, and Cullen, although he liked f!Mage, still tried to keep her at a safe distance. He wanted to be friends, I think. Until Uldred kicked that out of him.
Hm, I wonder if Cullen will have some extra content for a mage Quizzy who attempts to charm him out of his pants.
