I was an undercover agent trying to expose some person. Matthew Gray Gubler helped me with looking like a runway model so i can fit in. I saw Avan Jogia and knew i had to be with him to get closer to exposing the person. He invited me to his apartment along with some other girl and he asked me what type of drugs i used. i joked around and said "all of them" he brought out a joint so we all shared that. once we finished the joint he pulled out a tiny bag filled white powder. he snorted some and then offered me some, i declined and he said "I thought you said you do all of them" i told him that i was joking, that i didn't do coke or heroin, but for some reason i grabbed his head and licked the corner of his mouth, as some of the substance had fallen on his mustache. (i felt my tongue numbing? i heard that when you put coke in your mouth it numbs the area for a bit so that's what i'm assuming happened). he was a little surprised at what i did but wasn't against it, he just kept smiling at me. I realized that he may want to make a move on me so i quickly left the apartment. he started chasing after me, but i managed to get away from him and get in the van. Matthew Gray Gubler looked at me and said "well how'd it go? did you manage to get any information?" i said "not yet, i still need to spend more time with them, but it's a little tricky. i might have to do some drugs." He stayed quiet for a second but went "ya gotta do what ya gotta do." and then he started showing me some ways to make it look like your doing whatever drug, but not really. I woke up from there.
