1. I see implication.
Warn your sister to do away with this attitude she seems a bit too forward.
She must learn to conduct herself,excitement and reaction towards the things she sees.
She must learn to be " quick to listen slow to speak/react" to things lest this attitude land her in a place she may regret for the rest of her life.
Above all, pray for her that "every self infliction,destructive character that will land (mention her name) I cast u out of her in the mighty name of jesus" 2. Every infliction, implication,self destructive habit waiting land her in jail I disgrace u in the might name of jesus"
Now,whether she's too forward or not(naturally) the devil/enemy has already inflicted her so that she misbehave and it will cost her a lot. This is why it's a must she or you pray against this asap.
2. Not again, even you? Serpentine powers from your father's, or mother's house?
Seems it's not only your sister they are after they also want to implicate you.
This is a bit serious.
I see implication and a very complicated one before you.
You should dedicate 2night and wage war against "
Every serpentine powers waiting to strike, implicate me and (mention your sister name) receive the lord judgment and die.
Oh lord arise and scatter every serpentine arrow against me, inflicting me with arrow of implication by fire.
I dismantle every serpentine stronghold from my father's, mother's house shooting arrow of implicated against me and..
With psalm 119, 23,24,27.
....or one night/1 day vigil with fast.
Bless you.
