How can you prove a LACK of consent? For all we know she willingly went to his house and did drugs with him. 
How can groping be proven? 
Unless they had sex and traces of his semen were found in and on Audrey, I don't see how you can prove any of it in court.

Maybe she got the restraining order granted on the  basis of some other accusation, like stalking or harrassing, which can be easily proven with DMs and other digital records.
