is a taste test of energy drinks. their parents, who know the real reason they're here, agree to bring them because they believe there are important lessons to be learned. the first teen to figure out what to do will be 15-year-old chelsea. she's been dropped off at the party space ready for the taste test. she doesn't know o her mom is outside in a secret command center, outfitted with monitors hooked up to hidden cameras, so she can see chelsea's every move. >> tell me about your relationship with your daughter. >> we have a very open relationship. she's very mature for her age. >> she says chelsea who is an only child, would never post racy pictures of herself and she'd stop someone she knows from doing it. but at this party she's meeting everyone for the first time. >> how do you think your daughter will react in that situation? >> i'm not quite sure if she's going to say how inappropriate it is for him to do that in the

your kids to do the right thing, be more specific, and the best way to do that is through role playing. >> ask your child, what do you think you would say in this moment? if your child is like, i don't know, i would just handle it. no, what would you precisely say? keep role playing, all different kinds of situations so they gain the skill set for themselves. >> for this test, chelsea had to go it alone, but in this next group, three teens will be put to the test. will being in a group make it easier to step in. michaela is 17, zoe is 16 and kayla is 15. all their moms say they've spoken to their daughters about being careful when it comes to posting anything online. >> i talk to her about that often, especially with getting closer to college. >> michaela's mom says her daughter is the nurturing type. she's always looking out for her friends. >> you think she feels protective of others if they were in a situation -- >> i want to say yes. her friends always call her the mom.

bathroom. >> are you okay? >> that's when the actor let's them in on his plan. >> this is probably my chance, right now. >> this is your chance? >> when he leaves, corban and christian are very uncomfortable. >> i'll be right back. >> are you really? >> oh, god. >> but will they do anything about it? >> on the edge of your seat. >> i really am. >> listen to christian. through nervous laughter, he seems to grasp the seriousness of the situation. >> i swear, if they don't come out for like five minutes we're calling the police. >> corbin seems to hope everything will work out. while our actors are off in the bathroom, the boys sit and wait, and wait, and wait. >> this is awkward. then our actor, playing the

aggressor. >> what did you guys do? >> -- comes back alone. >> what happened? >> and starts to brag. >> she wanted to. it was good. >> the boys loughner vowsly, but never challenge him. it's hard for their moms to watch. >> not what i expected. >> he looks like he was uncomfortable. >> he did look like he was uncomfortable for most of up. but that nervous laugh that he did and really not -- i was expecting when they got up, he would have said something or at least tried to interfere in some kind of way and he didn't. >> danielle, whatnot what you expected of christian either? >> honestly, i didn't have real solid expectations. i thought this is invaluable. >> hi. >> their moms realize they did what most kids do, nothing, because they've never been taught how to deal with this a dangerous situation. >> all right. we're doing a show called "my kid would never do that."

it's really about helping parents learn to right ways to talk to their kids about situations like this. so corban, were you feeling uncomfortable at all? >> yes, but i didn't really know how to respond. >> your mom was saying i know in his mom he's like, i should do something, i should say something. but it's so hard to do that, right? >> yeah. >> i didn't know what to do. >> you know, i don't think a lot of us know what to do. >> i was just shocked. >> i kind of feel kind of bad now because i didn't do anything. >> to help them figure out what to do next time, we brought in our expert on addressing sexual assault. >> what do you think you could have said? is there anything you think you could have said. >> corban? >> i think i could have said maybe stop or lay off or something like that. >> this is realistic, isn't it? >> yeah, it is. >> christian, do you think if that was someone you cared for or loved across the way. >> i would do that. >> you would do what it takes. >> i was actually thinking

before, should i call the police. >> when they stand up you can say when you do that, i'm go toing call for help. that's not okay. >> i should stand up. even if it's one person, it makes me feel good. >> even if it doesn't go well, nothing feels better than knowing you did the right thing. >> doing the right thing when it comes to dating. dammish explains that even well meaning boys can make mistakes. >> the current system relies on body language which is the most unreliable form of choun case that exists. he says to make sure there's no miscommunication before making a move, you have to ask first. >> consent is everything. any sexual intimacy that's ever going to occur needs to be based on consent. >> corban being a good sport, agrees to be kuchd on how to ask for consent.

>> have you been having a good time? >> yeah, i've been having a really nice time. >> may i kiss you? >> damish tells the teens of course it's going to feel awkward. but he argues that it's worrying it. >> if you're not asked, how long would it have taken to go for the kiss if you don't ask. >> all night. >> all night, right? how long did that take? >> five seconds. >> here is where it gets fun, if she had said yes, would you have cared how awkward it was for the first five seconds? >> not at all. >> in fact, you would love hearing her say yes. >> yes. >> we say good-bye to this group and hello to these teens. this time we've added a girl. will that change the dynamic? >> i can totally get some right now, i swear to god. >> will she try to stop him. >> ll she try to stop him? >> i don't trust him. >> coming up, girls united or not? >> wow.
