The Cohens stood in their kitchen not speaking due to the bombshell they had just heard when Mike finally said something.

"So Dr. Roberts is my biological father huh," Mike stated

"Looks that way," Caleb responded

"So what does he want?" Sandy asked

"He doesn't want to challenge you and Kiki place as Mike's parents but he would like to spend some time with Mike." Caleb said

"Well that should be Mike's decision," Kristen said

"I think I could at least talk to him, will you guys come with me." Mike said

"Of course sweetie," Kristen replied

Mike, Kristen, Sandy, and Caleb made their way to the Robert's mansion. Dr. Roberts greeted them at the door and led them into the study. Everybody but Caleb and Dr. Robert's sat down. No one knew what to say until Mike spoke.

"So what kind of interaction are you looking for here?" Mike asked

"Well just to spend sometime together ball games, golf outings, those sorts of things." Dr. Roberts replied

"Why not?" Mike inquired

"Because I just figured out who you were and feel I should spend some time with you. I'm not trying to replace Sandy just to get to know my biological son." Dr. Roberts said

"I see," Mike replied

There was more silence before Mike spoke again

"So since you're my biological father that means Summer is my half sister," Mike pondered.

"Yes, that is correct," Dr. Roberts stated

Dr. Roberts then asked if something had happened between Mike and Summer. Mike said that Summer kissed him one time but Mike did not kiss her back due to the fact that Seth liked her. Caleb mentioned that it was a good thing Seth had a crush on Summer and everyone agreed. Mike then mentioned that it may be best if they didn't go public with this news. It would just seem to cause a scandal Mike thought and it would be weird to talk about Seth and Summer now or as Mike thought of it his brother who was dating his sister. Everyone agreed that this would be best and if Dr. Roberts and Mike ever did anything in public it would be because they had a common interest. Just as everyone was getting up to leave Summer entered the study to ask Dr. Roberts a question.

"Daddy I was wondering…oh what is going on here?" Summer inquired

"Nothing just some business," Dr. Roberts replied

"Then why is Mike here?" Summer asked

Dr. Roberts did not know what to say to this and Caleb finally spoke up saying it was probably best that Summer know the truth.

"Your right Cal and the truth is sweetie is that right before your mom was pregnant with you I had a one night stand with a maid in a hotel I was staying at and the product of that was Mike. I only found out today because I heard the same story from Sandy and did a DNA test to be sure. So bottom line is you now have a half brother." Dr. Roberts said

"So I have a brother? That could be cool," Summer said

Summer face suddenly went pale as she remembered she had once kissed Mike.

"Oh god I kissed my own brother, ew!" Summer squealed as she ran into the bathroom to brush her teeth and gargle with mouthwash.

Mike followed her and told her not to feel too bad its not like she knew and it was only a kiss with no tongue. Summer agreed and came out of the bathroom. Mike told her that they were keeping it under wraps as to not create a scandal. Mike also knew that he had to tell his brothers because if they found out he had been keeping this secret from them it could really hurt their bond. The consensus seemed to be this was a good idea.

That night Mike told his brothers and both took it well although Seth also thought it was a little weird that his brother was also a brother to his girlfriend but quickly moved on. Mike then moved on to talk about football as Harbor had a good chance to go undefeated this year. It had sure been an interesting day Mike though to himself.
