Mass Effect 2
I didn'tromance anyone and after the final mission I was not able to call Kelly. And yes I did flirt very hard with Kelly.
Jack? If I was going to be with her I would be afraid of getting more then just my feelings hurt.
Wiki sites are incredibly detailed - and they always warn before revealing spoiler material. In addition, I find these sites to be much more reliable than discussion boards.

Good point. Liara would probably wait until the Reapers are defeated, then tear Shepard to pieces. Talk about a painful way to die!
