In season 2 finale of HOUSE M.D.,
after being shot, the whole episode was House's hallucination.
In that whole sequence he realized that if given Ketamine, he might lose his brilliant mind but might regain his leg.
But when brought in E.R., he said to Cameron to ask Cuddy to give him Ketamine. Does that mean House was ready to compromise his brilliance in exchange for his leg functioning? I cannot digest it.
