Ryan and Bradley stepped through to another dimenension that looked no different to theirs, until they saw the doctor.
The doctor had what appeared to be a second head. It was exactly identical to his and had the same grin on both of his faces.
"Good, your here. We received a cross-dimensional message from our counterpart in your universe." The doctor said with his left head.
"As we see it, family members aren't born conjoined together in your universe, are they?" He said with his right.
"No, so everyone has at least one brother or sister?" Ryan said.
"Yes, thats right. Sometimes triples are born, or even quads, but where are our manners. I am Doctor Parker and well..." The doctor said with his left head.
"I am also Dr. Parker, considering we have the same last name. Hehe." His right head said, which was revealed as his twin brother.
"If you like, you can go out and explore this universe." Doctor Parker said, both of them together. Ryan and Bradley were already gone. They wanted to see how different this world was from theres.
