Erasmus was very entertained by the B story of this week's House, in which Dr. House comes closer to Mr. Holmes's lifestyle. Dr. Watson, er, Wilson, has moved into House's house at (cough) 221, apparently bringing with him his own Mrs. Hudson (a housekeeper played by Yareli Arizmendi). Erasmus needs to review Dr. House's domicile more closely to see if there's a Persian slipper nailed to the wall...
As far as the episode, "Clueless," went, Erasmus called the general solution early. However, the source of the problem was something of a violation of the fair-play canon that they generally adhere to. Mexico turned out to have been key, but beyond that, it was a bit impossible for the general viewer to guess. Still, pretty good stuff. And doubtless it was catnip for the fans rooting for Drs. House and Cameron's relationship.
(And, yes, Erasmus caught that Blackadder is on House's TiVo...)
