I do get the whole narrative within a narrative deal. But the first thing I noticed in Varric's story is that every women's boobies are bigger than their heads! Except for FemHawke's. Do you think it's out of his respect for her? Maybe he sees her as a little sister? Maybe he's afraid if she's listening, she'll kick his butt later?
I wonder how the real conversation went with Cassandra:
"So here is Hawke's sister and she had the biggest boobies ever! She casted a huge fireball that I could compare with the size of them. And her robes were pretty revealing. Did I tell you her boobies were really big?"
hehehe
