Don't lie for your W. Don't be an apart of her story/lie she's coming up with. She want to lie to her family let her do the lying. If she gets man about being caught or her family finding out, that means she know she is wrong and she should be up front with them and deal with the consequences or stop.
Next time, she ask you to tell her mother or any other person in her family a reason for her doing something, you should say, "If you want your mother/family to know where you are going to be you should tell her/him. If he/she ask me I won't lie, I don't know where you are going to be and that will be my answer, I don't know". You don't owe her anything, and you not need worry about her reaction to whatever the consequences that land her lap.
And here's a little secret, she's going to blame you no matter what happens or how her family finds out.
Stay strong Vik. You are an awesome man.
Onward and forward
