The truth about Callie's and Brandon's past got out by accident, sort of unplanned for any of the actors to reveal it to the kids. Seth and Beth were looking for answers who their parent's mystery lovers were and they had no luck with that. None of the family members wanted to talk about it. Stef even got so nervous and told them to put that to rest. That even got the kids more intrigued than anything else. There was some crazy mystery surrounding their parents' past and now they had to solve it. Mariana had no intention to tell them and start WWIII in their home, Wyatt kept quiet and Jude had a lot of reservations about talking about Callie's past. Seth knew his dad never knew who the man was, but he had to know at least something that could help. They had arranged to meet up after school because he had to tell Seth about his marriage and the new baby. AJ picked him up and Seth gave his car to Beth because his dad would bring him home after their lunch.
''Hi dad!''
''Hey son… How are you?''
''Good… I am good..''
''School?''
''It's ok. I am not complaining.''
''I am glad…Hm.. Did your mom mention something we have to talk about?''
''No… Why?''
''Hm… I met someone and I am getting married.''
Seth was happy for his dad, but a bit sad he knew nothing of it.
''You did? When?''
''Hm… Couple of months ago…''
''Cool… What is she like?''
''She is accountant, thirty years old, beautiful, fun.''
''When can I meet her?''
''I don't know. We'll see..''
''Oh, ok…''
They ordered the food.
''So, what does your girlfriend say about me? Is she ok with you having that old son?''
He was teasing him, but after few moments he noticed his father's serious face.
''You haven't told her?''
''Seth…''
''NO! She doesn't know about me.''
''It never came up.''
''I am your son, I am supposed to come up as soon as it becomes serious.''
''It's complicated. I don't think she would understand.''
''Whatever dad…''
Lunch came and they sat in silence. Seth decided to ask his dad about his mom's past.
''Dad, who did mom date before you?''
''That is a mystery. She never spoke of that man.''
''You know nothing?''
''I just know not to poke that bear.''
''What?''
''She gets crazy aggressive and defensive when I mention that.''
''I know. I had the same experience. Do you think he did something to her?''
''No, I think he just left.''
''Died?''
''I don't know.''
When he was close to the end of his food, he sent Beth message to pick him up from the restaurant. He was very hurt by his father and he really needed her. She showed up some twenty minutes later and he said good bye to his dad and left.
''Hey sexy, looking for a ride?''
That made him smile. Beth always knew how to make him smile. He got into the car and kissed her.
''I really needed that.''
''I am glad I could help. Where to?''
''Where are mom and your dad?''
''Out. It's Thursday, so they have some planes with uncle Matt and aunt Charlie.''
''I forgot it's nerd brigade date night.''
''Date night?''
''You know what I mean…''
''It sounds weird.''
''I know. But the weird thing is, I could see them dating.''
''Who?''
''Our parents…''
Beth made a face.
''Oh, my God!''
''What?''
''Maybe they did?! Maybe that is why no one talks about it?! Any other guy wouldn't be such a problem. She and your dad dated and somehow became siblings.''
''Seth, you must be high!''
''Think about it!''
''I am, and you are creeping me out.''
''Just look at them when we are at home. It does make sense.''
Beth did what he told her and started to notice that they didn't look at each other as the siblings usually do. They also found in Callie's room a picture of two of them that didn't really look sibling like. Stef took it after Brandon won the competition. He hugged her and they were grinning and glowing. No one found it unusual because everyone was happy for Brandon. But the look they shared, that was not how brother and sister look at one another. She put the photograph back into the hiding place and left the room.
Don't let him get you paranoid. You dad and aunt didn't date…it is just Seth's imagination. They were just close and good siblings. Beth repeated that to herself as a mantra for days.
Brandon and Callie started having doubts about the nature of Seth's and Beth's relationship, but they didn't mention it to one another. Each of them kept it to themselves and tried to find out more before they addressed the issue. Callie had few moments when she wanted to tell Brandon, but changed her mind. She didn't want the kids to have same experience as two of them did, so she choose to keep it quiet. Brandon had the same reasoning as she did. He felt bad for hiding it from Callie, but he couldn't address the issue without the evidence. Brandon came home a bit earlier and had a surprise of his life. He heard voices coming from the kids' side of the house at the time they were supposed to be at their friend's house. Callie had a thing with some of her friends and he was supposed to be at Stef's and Lena's but he changed his mind and just came back home. He climbed the stairs and followed directions of the voices. He saw his daughter and Callie's son kissing in their undies and getting into his bed. He quietly got down and left the house. He went to find Callie. He had to tell her now. She was having a drink with some of the teachers. She was surprised to see him at the bar. He told her he would be going home and now he was there.
''Hey, what are you doing here?''
''We must talk… It's important.''
She picked up her stuff and got into his car.
''What is going on?''
''In a minute… Wait just few minutes.''
He took her to the beach, to a place they spent a lot of time hiding from world. It was their place for big talks and important things.
''Brandon… What is going on?''
''Beth and Seth…''
''Are they ok?''
''I saw them having sex…''
She took a seat on the sand and he sat down too.
''Really?''
''Yes…''
''And what did you tell them?''
''I sort of just left… They haven't seen me.''
She didn't know why she started laughing, but she did. She actually knew why, she imagined Brandon walking into something like that. She remembered his face after he walked in on their moms and it was the same face now.
''It's not funny Callie!''
She started laughing even more after that comment. He gave her a look and she managed to stop.
''Ok…Ok… No more… So…You just left?''
''Yes, I wanted to see with you what is the right thing to do…''
''And you think I know?''
''No, but two heads can solve it better… Especially our heads. Their situation is a bit…hm…familiar…''
She saw how he blushed.
''Oh, my God! You are blushing!''
''It's not funny Callie… I am conflicted. That's why I need you.''
''Why our heads? Why you couldn't share it with someone else? Your mom? Mike?''
''Because we never had a chance to live our story. I don't want to do to them what my mom did to us…''
Smile was gone from her face.
''You are willing to let them date?''
''As much as it troubles me, I am. I don't want them to wonder what might have been if they had a chance…''
''You wonder?''
He turned towards her and hesitated.
''Every day… ''
She took his hand and they started leaning for a kiss. Before they had a chance to kiss,their phones started to ring. Stef and Lena were calling them. They answered their phones and moms told them to come home as soon as they could. They got into the car and drove home with so many thoughts in their heads. Callie was scared for the kids. If something happened to them or maybe some of their siblings. When they got home, they were surprised to see AJ also sitting there. Beth and Seth sat in the living room with their heads low. They noticed that she was crying and Seth was upset about something. Lena sat with her head in her hands and Stef sat with her arms crossed over her chest.
''What happened? What are you all doing here?''
Stef got up from the chair and turned towards Brandon and Callie.
''I found your children in bed together…Naked…''
Callie and Brandon just looked at one another, not knowing what to do or say next. Their train of thoughts was interrupted by AJ who got up and started shouting at his son.
''She is your sister! How could you?!''
