ok so my step dad thinks this is a hallutionaiton and at the end of the season thats when we find out it is so do you think that will really happen?????

No. We've already been told sa pamamagitan ng TPTB that it definitely was not a hallucination. Also, House has no reason to hallucinate since he is not on Vicodin and hadn't taken the Vicodin before Cuddy arrived. Remember, it was still in his hand. OTOH, I can understand people being suspicious, DS et al pag-ibig to screw with us. They're not now though.

It is not a hallucination. He didn't take the vicodin. This is not a dream. This is not a test. They have took the training wheels off and they are in it to win it.
Hugh sinabi "buckle up".

no. it's for real this time

No way! That would be totally lame! Plus that has already been done about twenty years nakaraan with the ipakita Dallas only it was with a dream. It pissed so many fans off people still talk about it to this day. Don't think the producers would be that stupid.
