okaaayyyy... no need to get slightly antagonistic, just trying to help
I'm not trying to be antagonistic. it just seriously made no sense for my character to help Serana at all. Ever. No matter how hot she is. I really think Bethesda dropped the ball on this one.
But what can you expect? Its not Morrowind.
The best anology I can come up with is this:
My character is a Navy SEAL tasked to kill terrorists. I find a terrorist carrying a nuclear bomb. So instead of killing the terrorist, I escort him to his hideout and help him deliver the bomb to his superiors. Then I have the option of either joining them, or leaving.
It MAKES NO SENSE AT ALL.
