"I'm really looking forward to having a big brother around," Brandon adds with a big smile, making the teen blush a bit.
Later, Bentley and Ryan step outside for a talk of their own. Ryan tells Bentley, "I'm excited for you. I'm excited for Brandon and Stella and Jagger," he says, referring to his other two children with ex MacKenzie Standifer.
After joking with Bentley about not sneaking out of the house, Ryan says, "When I was your age, I was most definitely running around. But you're a good kid, I don't have to worry about you."
Ryan then starts to reflect on the fact that Maci was just 16 when they had Bentley. "For the longest, I've not been in a good place. And there, for a while, your mama didn't want us together alone at all. I don't blame her. Yeah, it made me mad, but I don't blame her now."
He continued, "And now, your mom and I get along great. Taylor and I get along. We played golf and I enjoyed it. I wish we would have done it a lot sooner, but like I told Taylor when we was golfing, I wouldn't have wanted to deal with me then either, so I don't blame him. And your mama was just protecting you, and I don't blame her either."
"Sixteen years later, here we are. I'm sorry it took us so long, but it's better now than ever," Ryan says. "I'd love to spend more time with you whenever. And you can come over here because I know we ain't been able to, but I would enjoy that."
"I've never really gotten to spend a night at a house you've been in," Bentley says.
"I know, And if you're ever uncomfortable with anything, if you don't even want to tell me, just tell Mom and she'll tell me. But just let us know."
Bentley agrees to do that. Ryan concludes, "I think about this a lot. There were times, you know, that I wasn't there for you. But I hope, by showing you that it's a little different... I love you, though."
"I love you, too," Bentley says as the two hug.
Ahead of the big moment, Amanda opened up to Maci about what this move means to her and Ryan, who have each struggled in their relationship with their children as a result of their respective struggles with addiction.
"I'm excited. It's going to be new, it's going to be stressful, but we're all just learning to do this together. So it's really important for me and Ryan to bond with the kids and have them come over," she says, asking Maci if she'd be comfortable with Bentley staying there overnight.
"I'm okay with Bentley staying the night. This will honestly, it will be the first time where he goes to where Ryan is living and be happy about it," she says.
"That makes me happy, but I hate that it was like that," Amanda says.
