This season 5, episode 4 of the show House Birthmarks, is not about the traditional type of birthmark. It has nothing to do with the type of birthmark that some children are born with and have to deal with at least for the first few years of their lives.
House Birthmarks has to do with the marks that those that gave birth to you leave on you as you grow up. These birthmarks can leave lasting effects well into adulthood. The episode opens with a woman who is looking for her birth parents. She travels to China with an interpreter and approaches a couple who initially tell her that they never had a daughter.
As this woman is attempting to lift a Buddha to make a wish come true she collapses in the temple. She is brought to the hospital and House and company get to work on her trying to figure out this next mysterious illness to come down the pike.
So, not only is House trying to figure out what is wrong with the woman, he is also trying to find a way to get out of going to his father's funeral. Cuddy comes in and informs him he has a flight to catch and that his mother wants him to give the eulogy at the funeral. The he collapses in his office.
He wakes up in a car with Wilson driving. Wilson drugged him to get him to the funeral. Apparently House and his father rarely saw eye to eye and House refused to lie to his own mother by attending the funeral. Wilson and House find themselves in predicament after predicament including getting pulled over for speeding, getting arrested and taken to the police station.
As they stop at a rest stop, House talks about how bad it was growing up with his father and makes a deal with Wilson to go to the funeral if Wilson would give him his cane. Wislon bites and House knocks the car keys out of his hand with the cane into the sewer drain. When they finally get on their way again House pulls another stunt by jamming his cane onto the accelerator so they get pulled over by the cops.
Wilson tries to talk their way out of the ticket by telling the officers that House sped the car up with his cane jammed onto the accelerator but the officer does not believe him and he arrests them. House did all this just to delay the trip to the funeral.
Finally Wilson convinces the officer that House was only behaving like a child and they get released to continue on their way. House continues to try to solve the case back at the hospital with the help of his team. Everyone on the team feels that House is not dealing well with the death of his father, they just do not know the half of it.
House does not believe that his father is his birth father but he can't prove it. Blood tests do prove it however and Wilson and House go out to eat. Wilson admits that he had more fun on their trip than he has had in years and House birthmarks finally admits that his dad is dead.
