Yeah I know you needed to have that in for your own reasons and game purposes, but fact Julia leaves MC there drunk while she had the transport when brought him there, already reflects negatively enough on her as a friend and someone you can trust when it comes down to it.
Personally someone just walking away in such a situation without a word or warning in a swinging club would not be someone I would go out with again even if was a male friend or help me trust them. Let alone that it helps someone to be LI or even more wifey material.
Where I come from you do look out after your friends when go out with them and especially when they get drunk, whether they are male or female and I expect same from my female friends as well. Now that you may stop going out with them if they make it a habit of it is another thing.
