It was in the episode.
Wilson goes into House's office, they talk, House shows him the DNA test, then Wilson says something, "Well we don't get to choose who our parents are. I'm not even sure we get to choose who our friends are..."
"DELETE RECORDING. SAVE RECORDING"
Not that it's any consolation for you, but the same thing happened to me. I don't recall everything after that point, but I do remember the two of them walking back out of House's office, House stops and says, "my dad died." in a voice that is somewhere between blankness and realization
Trekker, Menu->Series Options->House->Stop Recording->Five Minutes after.
I've adjusted my own recording as well, especially given that I did not record thre trailer.
