She would have gone the whole nine yards if they had a condom....I'm sure of it. I have some mixed feelings about why she let him drink her blood. On the one hand because she couldn't go all the way and maybe wanted to satisfy him at least somehow. On the other hand maybe she also did it because it gives her a good feeling as well. I mean in the former books she always said how addicting it is when you get bitten.

That entire scene is just ..... well not bad but I don't know. I don't like it and I could have done without it. I guess it was somehow inevitable since they were together for quiet some time and after Dimitri's words: Love can fade. Mine has.
It's kinda understandable that she thinks Adrian is her only shot at a relationship and she likes him but seriously the blood thing was just unnecessary. I even get the live in the moment, don't waste time thing but again why the biting ?
