Transcript for Dad, teen adjust to life after weeks without video games: Part 6
Reporter: In Ohio, it's time for a change in latitude. Chris and MARIA are taking the kids for an adventure. Where are we going? We're going to Puerto Rico. Where are we going, Z.Z.? We're going to Puerto Rico. Reporter: They visit Puerto Rico every spring, but this year seems different. Going to the pool, going to the beach with my kids and my family and it's good. It's good to get away. It'd be easy if I could be on vacation all the time. Reporter: Weeks later, we drop in on Chris and MARIA on a Sunday morning. With 53 game-free days behind him, Chris is out of the basement and killing it in the kitchen. One morning several days earlier, MARIA recorded another video diary. It's her birthday. I really don't have big expectations for my birthday but imagine the surprise when I came downstairs to this. He got me a gift and beautiful flowers and a really nice card. I'm really feeling a lot of hope and excitement, and just some happiness. Your time at outback has come to an end but the journey continues. Reporter: After ten weeks unplugged in the wilderness, it's time for Josh to go home. I guess I get to sleep in a warm bed instead of on the ground in a sleeping bag. Reporter: Al and Christina are getting ready. Patching and painting Josh's room. Removing that custom built gaming computer. Ladies and gentlemen, it's our pleasure to welcome you to Detroit. Oh, boy. There he is. He's here. All right. Welcome home. Let me give you a real hug. Oh, you still smell like sage. Reporter: Home again, Josh has lost weight. He feels taller. And with a new haircut, he's a different boy. Now you've got to go back to reality. Yeah. Reporter: Those aren't the only changes. A couple days later, Josh has a follow-up brain scan. Dr. David Rosenberg shows us the results. Wow. What you can see here is, yeah, this is an oh, wow effect. Same boy. Reporter: Before treatment, after treatment. What is that telling you? He was completely shut down. When we talked with him here, he was exuberant. A different child. Reporter: In California, Brooke and her family work together on a sign of renewal, a fresh coat of paint. I'm wanting to start over and make my room more positive. I think if I can take my story and make other people think about things before they do it and help them to make a better life. I think that's really important to me. Reporter: And then it's time for Brooke to return to rehab. She's done well on this trial visit, but there's more to treating those underlying issues than simply taking her phone away. Yeah, this is the worst day of the whole trip. Every time. Sad that she's leaving, but super happy that, you know, she'll be back soon. Reporter: It may be a sign of her recovery that saying good-bye to her mom is harder than ever. Do you feel like you have your daughter back? No. I have the new and improved brookie. I do. And she's worked so hard.
